Current Johns Hopkins Hospital postings for Clinical Laboratory Scientist II positions in Baltimore start at $28.39 an hour and reach as high as $53.48 an hour, depending on the laboratory and position level considered. The Bureau of Labor Statistics reported a $29.75 national median hourly wage for clinical laboratory technologists and technicians in May 2024.
myJH is an institutional access portal, not a laboratory employer or compensation plan. Actual pay is determined by the Johns Hopkins entity, position, laboratory, schedule, credentials, and salary structure attached to the vacancy.
The current Johns Hopkins laboratory ranges
Two active Johns Hopkins Hospital listings illustrate how much variation can exist under the same broad job title.
A full-time day-shift Clinical Laboratory Scientist II posting listed a range of $28.39 to $46.87 an hour. A separate Clinical Laboratory Scientist II or III opening in the Transfusion Medicine Laboratory listed $28.39 to $53.48 an hour, with weekend rotations required. Both postings state that compensation is determined according to equity and experience for jobs with comparable scope and responsibility.
| Johns Hopkins Hospital posting | Published hourly range | Schedule detail |
|---|---|---|
| Clinical Laboratory Scientist II | $28.39–$46.87 | Full-time day shift |
| Clinical Laboratory Scientist II or III, Transfusion Medicine | $28.39–$53.48 | Full-time, 7 a.m.–3:30 p.m., weekend rotations |
| Histopathology Technician I | $26.58–$53.48 | Position-specific schedule |
| Pathologists’ Assistant II | $45.28–$74.76 | Surgical pathology role |

The ranges overlap, but the jobs are not equivalent.
A histopathology technician prepares tissue for microscopic examination. A clinical laboratory scientist analyzes patient specimens and may perform increasingly complex testing. A pathologists’ assistant carries a different educational and professional scope, including advanced surgical-pathology responsibilities.
Putting all three under one “Johns Hopkins lab salary” average would erase the qualifications that drive the difference.
What those hourly rates mean annually
At 40 paid hours a week for 52 weeks, the Clinical Laboratory Scientist II ranges would convert as follows:
- $28.39 an hour: approximately $59,051 a year
- $46.87 an hour: approximately $97,490 a year
- $53.48 an hour: approximately $111,238 a year
These are mathematical conversions from the published hourly rates, not annual salaries quoted by Johns Hopkins.
The distinction matters because actual annual earnings can change with weekly hours, unpaid leave, overtime, shift differentials, holiday work, or changes in schedule. Hospital laboratories may operate continuously, and BLS notes that laboratory technologists and technicians can work nights, weekends, and holidays because medical facilities remain open around the clock.
Do not add an assumed differential.
The reviewed Johns Hopkins postings do not publish one universal night, weekend, or specialty premium. A worker’s total compensation may exceed base pay, but no defensible amount can be assigned without a current policy or position-specific statement.
What BLS pay data actually shows
The BLS “Occupational Outlook Handbook: Clinical Laboratory Technologists and Technicians,” updated August 28, 2025, reports a national median of $61,890 annually, or $29.75 an hour, for May 2024. The lowest 10% earned below $38,020, while the highest 10% earned above $97,990.
Workers employed by private general medical and surgical hospitals had a higher median of $66,650. Educational services reported $62,470, medical and diagnostic laboratories reported $59,070, and physician offices reported $53,920.
| BLS benchmark, May 2024 | Annual pay |
| All clinical laboratory technologists and technicians | $61,890 median |
| Private general medical and surgical hospitals | $66,650 median |
| Educational services | $62,470 median |
| Medical and diagnostic laboratories | $59,070 median |
| Highest 10% of occupation | More than $97,990 |

The Johns Hopkins minimum of $28.39 an hour sits slightly below the BLS national median of $29.75. Its higher posted limits extend well beyond the BLS hospital median and, in the Transfusion Medicine listing, above the national top-10% threshold when converted to a full-time annual figure.
That does not mean a typical Hopkins scientist earns above the national 90th percentile.
A posting shows the possible hiring range for a named vacancy. BLS reports the middle worker across an occupation. The maximum and the median answer different questions.
Where the headline number misleads
“Johns Hopkins lab scientists can make $111,000” is arithmetically defensible and analytically incomplete.
The number comes from converting the $53.48 hourly maximum in a posting that may consider a Clinical Laboratory Scientist II or III. It does not establish the average pay for all Hopkins laboratory employees, the usual offer for a new hire, or the rate assigned to every Scientist II.
The lower boundary can be misused too.
A starting range of $28.39 does not mean every laboratory job at Johns Hopkins begins there. The Histopathology Technician I posting starts at $26.58, while the Pathologists’ Assistant II listing starts at $45.28.
The most useful salary factors are:
- exact classified title;
- Scientist II versus Scientist III consideration;
- clinical specialty;
- certification requirements;
- years and type of experience;
- worksite and employing Hopkins entity;
- shift and weekend obligations.
The title must come first.
A research technologist in a university laboratory should not be compared directly with a hospital clinical laboratory scientist solely because both work with specimens and equipment.
Clinical testing and research work are different labor markets
Johns Hopkins employs laboratory workers through both the university and health system.
Clinical laboratory employees perform patient testing used in diagnosis, treatment, and disease prevention. BLS says these workers analyze blood, urine, tissue, and other specimens; operate automated analyzers and microscopes; record test results; maintain equipment; and perform quality-control procedures.
Biological technicians generally support scientific investigation rather than routine clinical diagnosis. BLS describes their work as helping biological and medical scientists with laboratory setup, data collection, experiments, and observations.
Those occupational definitions produce different pay benchmarks.
BLS reported a $52,000 median annual wage for biological technicians in May 2024. The median was $60,830 in scientific research and development services, $51,300 in state colleges and universities, and $48,490 in hospitals.
Indeed’s Johns Hopkins University page estimated average Research Assistant pay at $21.35 an hour, based on 105 past and present job postings, and described the estimate as 14% above its displayed national comparison. Indeed expressly warns that its numbers are approximations based on third-party submissions and should not replace the employer’s actual salary information.
The source hierarchy is clear:
- Current official position range.
- Official Johns Hopkins salary structure.
- BLS occupational benchmark.
- Third-party posting or self-reported estimate.
Indeed can suggest a pattern. It cannot override a current Johns Hopkins posting.
The Johns Hopkins salary structure behind university roles
Johns Hopkins University says it assigns every staff job a salary range based on market value and reviews its ranges annually. Its FY2026 structure separates Administrative Technical Operations, Academic/Clinical/Research Operations, Administrative Technical Professional, Academic/Clinical/Research Professional, and leadership roles.
This structure explains why similar-sounding jobs can produce different ranges.
A role classified as laboratory operations may sit in a different compensation family from a professional scientist, research coordinator, or clinical laboratory employee working for the hospital. The classified role, level, and range provide more useful information than the everyday title alone.
Johns Hopkins also states that its career architecture is intended to create greater transparency around job opportunities and career levels. Employees can view that structure through the myCareer system.
That does not create automatic advancement.
Moving to a higher career level generally requires a role with greater responsibility, different qualifications, or a new position classification. Length of service alone does not prove that a worker belongs at the next level.
Education and certification affect the pay comparison
BLS says clinical laboratory technologists typically need a bachelor’s degree. Technicians may qualify with an associate degree, and some states require licensing. Employers may also prefer professional certification.
Technologists generally perform more complex testing and carry greater quality-assurance responsibility than technicians. Technicians often perform more routine or automated procedures under broader supervision.
The distinction helps explain the wide Johns Hopkins laboratory ranges.
A position involving transfusion medicine, complex manual testing, quality control, troubleshooting, regulatory documentation, or Scientist III responsibilities may be positioned differently from a routine support role.
Credentials can also be specialty-specific.
Histotechnicians prepare and stain tissue. Transfusion-medicine workers deal with blood-bank processes. Pathologists’ assistants work in surgical pathology. Their education and certification pathways are not interchangeable, even when all appear in the same Laboratory/Pathology category.
The category is broad. The qualifications are not.
Job growth is modest, but replacement hiring is large
BLS projects employment of clinical laboratory technologists and technicians to grow 2% from 2024 to 2034, from 351,200 to 357,200 jobs. That equals approximately 6,000 net additional jobs over the decade.
At the same time, BLS projects approximately 22,600 openings each year.
Most are expected to result from workers changing occupations or leaving the labor force rather than newly created positions.
This is a useful reality check.
A figure of 22,600 annual openings sounds like rapid expansion. The occupation’s projected net growth is only 2%. Replacement demand creates most of the hiring activity.
BLS expects greater diagnostic need as the population ages and testing expands for illnesses such as cancer and type 2 diabetes. Genetic testing also supports demand. Automation, however, is expected to restrain employment growth by allowing laboratories to process more tests with fewer manual steps.
Demand remains. Productivity changes the headcount.
Research technician growth follows a similar pattern
Biological technicians have a projected 3% employment increase from 2024 to 2034, matching the average for all occupations. BLS expects approximately 9,100 openings annually, with many again caused by replacement rather than expansion.
Medical scientists have a stronger outlook.
BLS projects 9% growth for medical scientists from 2024 to 2034, with approximately 9,600 openings per year. Those positions usually require doctoral or professional education and should not be treated as the direct next salary level for every laboratory technician.
The progression is not automatic:
- technician roles support laboratory execution;
- technologist or scientist roles can involve more complex testing or professional responsibility;
- medical scientists design and lead research requiring advanced education.
Experience can support progression, but education, certification, scientific independence, and vacancy availability shape the route.
Hospital laboratories carry operational friction
Clinical laboratory work is not a standard office schedule.
The Transfusion Medicine listing specifies a 7 a.m. to 3:30 p.m. schedule with weekend rotations. BLS says hospital laboratory workers may work nights, weekends, and holidays. It also identifies exposure to biohazardous materials, repetitive-motion risks, prolonged standing, and the need for protective equipment and safety procedures.
Those conditions are part of the compensation comparison.
A day-shift research position and a weekend-rotation clinical position may show similar annualized pay while imposing different scheduling and safety demands.
Base salary alone does not capture that difference.
The public postings reviewed do advertise tuition assistance, career development, and a comprehensive benefits package, but they do not assign a dollar value to those items within the vacancy.
No benefit value should be added to the hourly rate without plan-specific calculations.
What third-party salary estimates get wrong
Third-party websites often merge nearby but nonidentical titles.
“Lab technician,” “research technician,” “research technologist,” “medical technologist,” and “clinical laboratory scientist” can produce substantially different estimates. A site may also combine Johns Hopkins University with Johns Hopkins Hospital or the wider Health System.
That creates three recurring errors:
- mixing university research roles with patient-testing jobs;
- combining entry-level technicians and certified scientists;
- presenting an estimated average as if it were an official offer.
Indeed’s Research Assistant estimate of $21.35 an hour is based on posting-derived data and is explicitly labeled approximate. The current official Hopkins clinical-scientist ranges begin higher, but they describe a different occupation with different requirements.
The apparent conflict disappears once the titles are separated.
Data limitations
The reviewed official job postings provide exact ranges but do not disclose the actual salary selected for the successful applicant.
BLS publishes national occupational medians, not Johns Hopkins-specific averages. Its category combines clinical technologists and technicians, whose responsibilities and education can differ.
Indeed estimates are based on third-party submissions and historical or current postings, with no guarantee that every record uses the same title definition, schedule, or Johns Hopkins employing entity.
No consolidated public dataset was located showing:
- median pay across all Hopkins laboratory employees;
- average shift differentials;
- pay by certification;
- typical placement within each posted range;
- turnover by laboratory specialty;
- promotion rates from technician to scientist;
- average time required to reach a senior laboratory role.
A precise estimate must remain position-specific.
Frequently asked questions
Does myJH determine laboratory pay?
No. The employer and position do.
What does a Johns Hopkins Clinical Laboratory Scientist II earn?
Two reviewed Baltimore postings listed $28.39 to $46.87 an hour and $28.39 to $53.48 an hour. The higher range could consider Scientist II or III candidates.
What is the national laboratory-scientist median?
BLS reported $61,890 annually, or $29.75 an hour, for clinical laboratory technologists and technicians in May 2024.
Do hospital laboratory workers earn more nationally?
BLS reported a $66,650 median for workers in private general medical and surgical hospitals, above the occupation-wide median of $61,890.
Is a research technologist the same as a clinical laboratory scientist?
No. Research roles generally support scientific studies, while clinical laboratory scientists perform patient testing used in diagnosis and treatment. Individual duties can overlap, but the occupational and salary comparisons are different.
Are laboratory jobs growing quickly?
Not by net headcount. BLS projects 2% growth for clinical laboratory technologists and technicians from 2024 to 2034, but approximately 22,600 annual openings, primarily due to replacement needs.
What education is normally required?
BLS says technologists typically need a bachelor’s degree, while some technician positions accept an associate degree. Licensing or certification requirements can vary by state and employer.
Why do two Hopkins scientist postings show different maximums?
One listing was limited to Clinical Laboratory Scientist II, while the Transfusion Medicine posting could consider Scientist II or III. Specialty, experience, responsibility, and internal equity can also affect the range.
The most defensible pay figure is the range attached to the exact laboratory position, followed by the BLS benchmark for the matching occupation rather than a generic “myJH laboratory salary” estimate.
