Bihar Lab Technician Exam Pattern, Eligibility
114 topics across 4 subjects. Every question carries a written explanation.
There is no exam called Bihar Lab Technician. The Bihar Technical Service Commission's recruitments listing, read in full on 12 September 2026, advertises nothing under that name. You almost certainly want Advertisement No. 02/2025, Laboratory Technician in the Health Department, covered in full on our BTSC Lab Technician page.
BTSC recruits two laboratory posts that are easy to mix up. Same fee and same marking, but almost nothing else in common, and a candidate eligible for one usually isn't eligible for the other.
| Laboratory Technician | Laboratory Assistant (Science) | |
|---|---|---|
| Hindi name | Prayogshala Pravaidhik | Prayogshala Sahayak (Vigyan) |
| Advertisement | No. 02/2025 | No. 12/2026 |
| Requisitioning department | Health | Science, Technology and Technical Education |
| Where the job is | Government hospitals and health institutions | Technical education institutions |
| Qualification | 10+2 with Physics, Chemistry, Biology and English, plus a Diploma in Laboratory Technician or a Bachelor of Medical Laboratory Technology | A graduate degree in Physics, Chemistry or Mathematics from a university established under the University Grants Commission Act or a Deemed University |
| Pay | Level 5, grade pay ₹2,800 | Level 6, entry pay ₹35,400, non-gazetted |
| Posts advertised | 2,969 | 164 |
The quick test: a medical laboratory diploma means Laboratory Technician; a science degree in physics, chemistry or mathematics means Laboratory Assistant (Science), which pays a level higher.
BTSC also advertises Laboratory Assistant posts for a dozen engineering branches, from Civil and Electrical to Ceramics, Printing and Textile Engineering. Those are different posts again.

Bihar Lab Technician Details
Exam Pattern
Both posts use the same computer based test format.
| Questions | 100 multiple choice, objective |
| Marks | 100 |
| Duration | 2 hours |
| Language | Hindi and English |
| Marking | +1 for a correct answer, −0.25 for a wrong one |
| Shifts | More than one, with normalisation applied to the result |
The subject and level differ. Laboratory Technician is set on the two-year Diploma in Medical Laboratory Technician curriculum; Laboratory Assistant (Science) on graduate physics, chemistry or mathematics. There's no sectional timing in either.
Eligibility Criteria
Both are open to Indian citizens, but reservation is only for permanent residents of Bihar, decided on the permanent address in the online form.
| Laboratory Technician, Advt 02/2025 | Laboratory Assistant (Science), Advt 12/2026 | |
|---|---|---|
| School | Intermediate or 10+2 with Physics, Chemistry, Biology and English | Not separately specified; the degree is the requirement |
| Professional | A Diploma in Laboratory Technician course or a Bachelor of Medical Laboratory Technology from an institution recognised by the Union Government, the Government of Bihar or another state government | A graduate degree in Physics or Chemistry or Mathematics from a university established under the University Grants Commission Act, or a Deemed University |
| Age, minimum | 18, as on 1 August 2024 | As stated in that advertisement |
| Age, maximum | 37 unreserved, 40 unreserved women and Backward and Extremely Backward Class, 42 Scheduled Caste and Scheduled Tribe | The same category structure |
Standard relaxations for both: ten years for persons with disabilities, five for Bihar government servants with three years of continuous regular service, and the length of prior contract service in the same post. Only one can be claimed.
The Laboratory Technician advertisement also keeps eligible anyone who was within the upper age limit at any point between 1 August 2014 and 1 August 2024.
Reserved categories in both: Scheduled Caste, Scheduled Tribe, Extremely Backward Class, Backward Class, Economically Weaker Section and Women of Backward Classes, plus 35 per cent horizontal reservation for women domiciled in Bihar and 2 per cent for grandchildren of freedom fighters. BC and EBC candidates need a non-creamy-layer certificate issued for the Government of Bihar; for women it must be in the father's name and address.
Selection Process
No interview for either. Merit is out of 100:
| Component | Marks |
|---|---|
| Written competitive examination, a computer based test | 75 |
| Contract service in the same post, 5 marks a year, capped | 25 |
| Total | 100 |
Your test percentage is multiplied by 0.75, so 50 per cent in the paper is 37.5 marks. Experience marks go only to those who qualify the test, and only for contract service in the same post, certified on the Appendix-1 format in the advertisement. Service as a medical laboratory technician earns nothing towards Laboratory Assistant (Science), and the reverse. Document verification follows.
How to Apply
Apply online only at btsc.bihar.gov.in, paying by debit card, credit card, internet banking or UPI. The fee is the same for both posts.
| Candidate | Fee |
|---|---|
| General, Backward Class, Extremely Backward Class, Economically Weaker Section | ₹600 |
| Scheduled Caste and Scheduled Tribe, permanent residents of Bihar | ₹150 |
| Women of any category, permanent residents of Bihar | ₹150 |
| Candidates resident outside Bihar, any category, any sex | ₹600 |
| Persons with disabilities, any category | ₹150 |
Each advertisement is a separate application and fee. If you pay a concessional fee and can't produce the certificate behind it, your candidature is cancelled. Reservation, disability, freedom-fighter descent and experience each have their own column in the form and can't be added later, and the category can't be changed after registration.
Participating Institutes
BTSC runs both recruitments on requisition from different departments.
Laboratory Technician, Advertisement No. 02/2025
Health Department, Government of Bihar: 2,969 posts in its hospitals and health institutions, including 766 for women, 90 for persons with disabilities and 45 for grandchildren of freedom fighters.
Laboratory Assistant (Science), Advertisement No. 12/2026
Science, Technology and Technical Education Department, on a requisition of 26 December 2024, for 164 posts.
| Category | Posts | Of which for women |
|---|---|---|
| Unreserved | 65 | 23 |
| Economically Weaker Section | 16 | 6 |
| Scheduled Caste | 27, including 1 backlog post | 9 |
| Scheduled Tribe | 2 | 0 |
| Extremely Backward Class | 30, including 1 backlog post | 10 |
| Backward Class | 19 | 7 |
| Women of Backward Classes | 5 | Not applicable |
| Total | 164 | 55 |
Seven are for persons with disabilities (two each for blindness and low vision, deafness and hard of hearing, and locomotor disability; one for autism, intellectual disability, specific learning disability and mental illness or multiple disability) and three for grandchildren of freedom fighters, all for domiciles of Bihar.
Important Dates
BTSC has no annual calendar. It advertises a post when the requisition arrives, so these two ran more than a year apart.
| Stage | Laboratory Technician, 02/2025 | Laboratory Assistant (Science), 12/2026 |
|---|---|---|
| Requisition received | Through the General Administration Department | 26 December 2024 |
| Online registration opens | 4 March 2025 | 6 April 2026 |
| Online registration closes | 1 April 2025 | 6 May 2026 |
| Crucial date for age | 1 August 2024 | As stated in that advertisement |
Watch the Recruitments listing, which carries every advertisement with its dates.
Cut Off
Minimum qualifying marks in the written test are Bihar-wide, set by state resolutions of 16 July 2007 and 22 January 2021, and the same for both posts:
| Category | Minimum qualifying marks in the written test |
|---|---|
| General | 40% |
| Backward Class | 36.5% |
| Extremely Backward Class | 34% |
| Scheduled Caste and Scheduled Tribe | 32% |
| Women of any category | 32% |
| Persons with disabilities | 32% |
Below your category's minimum, experience doesn't help.
No closing marks have been published for either laboratory post yet. BTSC prints them out of the combined 100 with each result on its result page. For comparison, its 2025 health recruitments closed at 30.5625 for Pharmacist, 32.8125 for Operation Theatre Assistant and 41.6250 for X-Ray Technician.
Preparation Tips
- Settle which post you mean. Medical laboratory qualification: Laboratory Technician. Science degree: Laboratory Assistant (Science). Different syllabus, pay and vacancies.
- Read that post's own syllabus on the syllabus page, filed under the post's name. BTSC has more than a dozen laboratory-related syllabi, so match the name exactly.
- Count your experience marks. Up to 25 of the 100 come from contract service in the same post, five a year with part-years prorated. Several years banked means you need a lower test score for the same rank.
- Answer everything. A guess is worth a quarter of a mark on average, and there's no sectional timing.
- Get the certificates right: permanent residence for reservation, and the Bihar non-creamy-layer certificate for BC and EBC.
