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.

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.

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 02/2025Laboratory Assistant (Science), Advt 12/2026
SchoolIntermediate or 10+2 with Physics, Chemistry, Biology and EnglishNot separately specified; the degree is the requirement
ProfessionalA 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 governmentA graduate degree in Physics or Chemistry or Mathematics from a university established under the University Grants Commission Act, or a Deemed University
Age, minimum18, as on 1 August 2024As stated in that advertisement
Age, maximum37 unreserved, 40 unreserved women and Backward and Extremely Backward Class, 42 Scheduled Caste and Scheduled TribeThe 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:

ComponentMarks
Written competitive examination, a computer based test75
Contract service in the same post, 5 marks a year, capped25
Total100

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.

CandidateFee
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.

CategoryPostsOf which for women
Unreserved6523
Economically Weaker Section166
Scheduled Caste27, including 1 backlog post9
Scheduled Tribe20
Extremely Backward Class30, including 1 backlog post10
Backward Class197

Total16455

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.

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:

CategoryMinimum qualifying marks in the written test
General40%
Backward Class36.5%
Extremely Backward Class34%
Scheduled Caste and Scheduled Tribe32%
Women of any category32%
Persons with disabilities32%

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
  1. Settle which post you mean. Medical laboratory qualification: Laboratory Technician. Science degree: Laboratory Assistant (Science). Different syllabus, pay and vacancies.
  2. 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.
  3. 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.
  4. Answer everything. A guess is worth a quarter of a mark on average, and there's no sectional timing.
  5. Get the certificates right: permanent residence for reservation, and the Bihar non-creamy-layer certificate for BC and EBC.
