Medical Laboratory Scientist
Health & Medicine
Medical laboratory scientists run the tests that doctors rely on to make a diagnosis. They receive blood, urine, stool, tissue and swab samples, prepare and analyse them using microscopes, analysers and chemical reagents, and report results — malaria parasites, blood counts, blood grouping and cross-matching for transfusion, HIV and hepatitis screening, cultures to identify bacteria and which antibiotic will kill them, and chemistry tests for kidney, liver and blood sugar. They also maintain machines, control reagent quality and keep records. The field has sections — chemical pathology, haematology and blood transfusion, medical microbiology and parasitology, histopathology and immunology — and most scientists eventually specialise. In Nigeria they work in teaching and general hospitals, private diagnostic laboratories, blood transfusion services, public health laboratories and NCDC-linked facilities, research institutes such as NIMR, and pharmaceutical and reagent companies. Many later open their own licensed diagnostic laboratory. It suits students who like Biology and Chemistry, are careful and methodical, and are comfortable with handling samples and following procedures exactly, since a careless result can mean a wrong treatment.
Exam requirements
Career pathway
Science subjects at SSCE
At SSCE level
Five credits at not more than two sittings including English Language, Mathematics, Biology, Chemistry and Physics.
UTME and admission into Medical Laboratory Science
Sit JAMB UTME with English, Biology, Chemistry and Physics, then pass post-UTME. Apply to a university whose programme is accredited by the Medical Laboratory Science Council of Nigeria (MLSCN) — this matters, because an unaccredited programme will not get you licensed.
B.MLS degree
5 years
Five years covering chemical pathology, haematology and blood group serology, medical microbiology and parasitology, histopathology and immunology, with laboratory postings in a teaching hospital.
Internship/housemanship in an approved laboratory
1 year
A supervised year in an MLSCN-approved hospital laboratory, rotating through the main sections. Places are competitive and you apply to teaching and federal medical centres directly.
MLSCN licensing examination and registration
You must be registered and licensed by the Medical Laboratory Science Council of Nigeria to practise. Registration involves the Council's qualifying/licensing requirements and an annual practising licence; confirm the current examination and fee requirements directly with MLSCN as they are periodically revised.
NYSC
1 year
National Youth Service, usually after internship. Many are posted to hospital laboratories and retained afterwards.
Specialisation or further study
Options include the Associateship/Fellowship of the Medical Laboratory Science Council in a speciality, or an M.Sc and Ph.D for research, teaching and laboratory management roles.
Common challenges
Confusing it with being a laboratory technician
ModerateStudents and even some relatives do not know the difference between a Medical Laboratory Scientist (degree, MLSCN-licensed), a technician and an assistant, and some end up on a course that does not lead to licensing.
How to handle: Before you accept any admission, check the MLSCN website or call the Council to confirm the school and programme are accredited for Medical Laboratory Science. Be careful with private 'lab training' schools that advertise quick certificates — they do not make you a licensed scientist. If you are offered Biochemistry or Microbiology instead, know that it is a different career, not a shortcut into this one.
Securing an internship place
DifficultThe one-year internship is compulsory before full practice, but approved hospital places are limited and many graduates wait months after finishing school.
How to handle: Start early: from 500 level, collect the application requirements of several teaching hospitals and federal medical centres across different states, not just the one near you, and be willing to travel. Keep your results and clearance documents ready so you can apply the moment adverts open, and ask recent graduates from your department which hospitals advertise and when.
Exposure to infection and hazardous samples
ModerateYou handle blood and other samples that may carry HIV, hepatitis B, tuberculosis or Lassa fever, sometimes in laboratories with imperfect safety supplies.
How to handle: Take hepatitis B vaccination and get the full course — do not skip doses. Learn and keep to standard precautions from your student days: gloves, lab coat, no eating in the lab, correct sharps disposal. If a workplace does not supply gloves and disinfectant, raise it formally with the laboratory manager rather than quietly working without them.
Broken equipment and reagent shortages
ModeratePublic laboratories often have analysers out of service or run out of reagents, which forces manual methods, slows work and frustrates staff.
How to handle: Keep your manual skills sharp — microscopy, manual cell counts, blood grouping — because they are what still work when a machine is down, and they make you valuable. Learn basic troubleshooting and maintenance of the analysers you use, and document faults properly so management has a record to act on.
Friction over roles in the hospital
ModerateThere are long-running disputes in Nigerian health facilities over professional roles, who signs results and relative pay between health workers, which can be discouraging early on.
How to handle: Know your scope of practice from the MLSCN rules and work within it confidently. Join your professional association (AMLSN) as a student and later as a member so you are informed and not isolated. Focus your energy on becoming excellent at a speciality — good scientists get referred work and respect regardless of the politics.
