BTSC Lab Technician Syllabus, Exam Pattern, Eligibility

Your test percentage is multiplied by 0.75 for the merit list; the advertisement's own example is 50 per cent becoming 37.5 marks. Because of normalisation, a raw score from one shift can't be compared directly with another shift or with a published cut-off.

The D.M.L.T. syllabus isn't a topic list. It's the curriculum of the two-year Diploma in Medical Laboratory Technician run by Bihar's Department of Health, Medical Education and Indigenous Medicine, with its own marks scheme.

Each year also has a 100-mark practical and a 40-mark viva, which a written test can't cover. Of the seven theory papers, four are second-year, and microbiology (bacteriology and virology, serology and mycology) takes two. Biochemistry is taught as method, so expect questions on how an estimation is done. Bihar pairs histopathology with animal care, which generic D.M.L.T. books may not. B.M.L.T. holders sit the same diploma-level paper.

Open to Indian citizens. Reservation is only for permanent residents of Bihar, going by the permanent address in your form.

Qualification

Age

Minimum 18 years as on 1 August 2024, by the date on your matriculation certificate.

Relaxations (one only)

• Persons with disabilities: ten years (GAD resolution 962 of 22 January 2021).
• Bihar government servants with three years' regular continuous service: five years.
• Contract service as a Lab Technician: relaxed by the full length of that service to 1 August 2024, part-years included, in a Bihar state government hospital or institution, or a non-private hospital under the central government, a panchayati raj body or an urban local body.
• Ten-year carry-forward: the last Lab Technician advertisement counted age from 1 August 2014, so anyone within the upper limit at any point between 1 August 2014 and 1 August 2024 can still apply.

Reservation

SC, ST, EBC, BC, EWS and Women of Backward Classes (a separate category in Bihar), plus 35 per cent for women (subject to vacancies) and 2 per cent for grandchildren of freedom fighters on a central pension, by a District Magistrate's certificate in the prescribed format. An identity letter calling you a freedom fighter's successor isn't accepted. Transgender candidates get Backward Class benefits under a GAD letter of 12 September 2014.

Certificate rules

• Claim reservation in the form. It can't be added later, and category can't change after registration.
• BC and EBC need a Bihar non-creamy-layer certificate; a caste certificate alone isn't enough. Women's certificates must be in the father's name and address.
• An EWS certificate is valid for one year from issue.
• Disability: Appendix-1 format from a medical board, uploaded with the form; no expired temporary certificates; Form VI under the RPwD Rules, 2017 for multiple disabilities. BTSC re-examines disability through its own medical board.

No interview.

1. Computer based test, scaled to 75 marks.
2. Category minimum (below). Miss it and you're out.
3. Experience marks, added only if you qualify.
4. Category-wise merit list out of 100.
5. Document verification.

So an unreserved woman qualifies at 32 per cent where an unreserved man needs 40.

Experience marks

Five per year, up to 25, for contract service in the same post in a Bihar state government hospital or institution, or a non-private hospital under the central government, a panchayati raj body or an urban local body. Part-years: working days × 5 ÷ 365. Service counts to 4 March 2025.

The certificate must be in the Appendix-1 format attached to the advertisement, signed by the district Civil Surgeon, a medical college Principal, a medical college hospital's Superintendent, a super-speciality hospital's Director, or the head of another named institution. Any other format earns nothing, and if you don't claim it in the online form you get neither marks nor age relaxation.

X-Ray Technician and Operation Theatre Assistant are on the same level. Tutor (Nursing), advertised later the same year, is Level 8 with grade pay ₹4,800. Allowances follow state rules and aren't in the advertisement.

Online only, on btsc.bihar.gov.in. Pay by debit card, credit card, net banking or UPI; the bank adds its charge.

If you pay the reduced fee and later can't produce the certificate, you lose your candidature. Paying the general fee avoids that risk.

Gather these first

• original matriculation certificate (it fixes your date of birth);
• 10+2 marksheet and certificate;
• marksheets for every year of the diploma or B.M.L.T., and the certificate;
• caste, non-creamy-layer or EWS certificate;
• domicile certificate, needed for any reservation;
• Appendix-1 experience certificate, if claiming experience marks.

Each claim (reservation, disability, freedom-fighter descent, experience) has its own column in the form, and anything left out can't be claimed later.

All posts are for the Health Department, Government of Bihar, Patna, in its hospitals and institutions across the state.

The women's share depends on vacancies, so it isn't a flat 35 per cent of each row. 90 posts are for persons with disabilities: 22 blindness and low vision, 22 deafness and hard of hearing, 23 locomotor disability (including cerebral palsy, leprosy cured, dwarfism, acid attack and muscular dystrophy), and 23 autism, intellectual disability, specific learning disability, mental illness or multiple disability. Another 45 are for grandchildren of freedom fighters. The total may rise or fall if more requisitions arrive.

The test runs in several shifts. Centres are announced with the admit card on btsc.bihar.gov.in, not in the advertisement, and there's no promise of your home district. Where you're posted later is up to the Health Department.

BTSC doesn't publish a yearly calendar; it advertises when a department sends a requisition. For Advertisement No. 02/2025:

Note that age is fixed seven months before the advertisement, while experience runs to the advertisement date. Operation Theatre Assistant, ECG Technician and X-Ray Technician (Nos. 03 to 05/2025) used the same 4 March to 1 April window.

Download it under Admit Card / Call Letter on btsc.bihar.gov.in. The date is notified separately. It also shows your shift.

Afterwards, scores go up under Score Card, and answer-key or result objections go through the Objection Portal, filed under the right advertisement number within the window BTSC announces.

Results appear advertisement by advertisement under Result on the BTSC site, with individual scores on the Score Card page.

The score shown is normalised, not a count of correct answers. Your merit position adds up to 25 experience marks to the 75 from the test, so two people with the same test score can be far apart. Qualified candidates are listed category-wise and called for document verification of every claim.

The only figures BTSC publishes in advance are the category minimums in Selection Process (40% General down to 32% for SC, ST, women and PwBD). These come from Bihar-wide resolutions of 16 July 2007 and 22 January 2021.

No closing marks for this post have been published. The actual cut-off out of 100 will be well above the minimum with 2,969 posts shared on combined marks, and it appears with the result on the BTSC Result page.

1. Count your experience marks first. Five a year, up to 25. With four years banked you need a much lower test score than someone with none. Get the Appendix-1 certificate signed by the right officer before you apply.
2. Revise the Bihar diploma curriculum, all seven theory subjects, with extra time on the four second-year papers.
3. Attempt everything you can. The penalty is a quarter mark and there's no sectional clock.
4. Set targets after the multiplier. Sixty per cent in the test is 45 marks, not 60.
5. Check the ten-year age clause (clause 2(v)) before deciding you're too old, and pick whichever single relaxation helps most.
6. Get the right certificates, especially the Bihar non-creamy-layer one in your father's name if you're a woman.

BTSC publishes no previous papers or model paper for Lab Technician. A "BTSC Lab Technician previous year paper" on sale anywhere didn't come from the Commission.

10+2 with Physics, Chemistry, Biology and English, plus a Diploma in Laboratory Technician or a B.M.L.T., with the certificate in hand.

It's multiplied by 0.75. Fifty per cent becomes 37.5.

Yes, as unreserved, paying ₹600.

What is the fee?

₹600, or ₹150 for Bihar SC, ST and women, and for all PwBD candidates.
