Biological Technician
Set up and run laboratory experiments for biologists and medical researchers.
Test blood, tissue and body fluids to help doctors diagnose patients.
Medical laboratory technologists analyze patient samples for cell counts, blood type, infections and chemical levels, check that results are accurate, and report them to physicians. They operate automated analyzers and microscopes, follow strict quality-control procedures, and work in hospital or clinical labs. Entry is a bachelor's degree in medical laboratory science plus certification; technician roles accept an associate degree.
Take these courses in order, from beginner to mid-level.
The shared base every STEM career uses: working with numbers and units, testing ideas fairly, handling data and code, and explaining your work.
Biology, chemistry, the lab mindset, the regulated routes in, and the rules that govern real labs.
The everyday computer, internet, safety and AI skills every tech and STEM job assumes you already have.
Write clear emails and documents, present and run meetings, work well on teams, and navigate résumés, interviews and networking.
The practical math behind tech and STEM work: numbers, algebra, functions, geometry, logic and counting, with short code exercises.
Clean tables, correct formulas, lookups, pivot tables and honest charts in Google Sheets, LibreOffice Calc or Excel.
Describe data, reason with probability, and draw honest conclusions from samples, with short fill-in-the-blank Python exercises.
Recognise lab hazards, read GHS labels and Safety Data Sheets, choose PPE, and understand the training and records that keep labs safe.
Atoms, bonding, gases, balanced equations, moles, solutions, pH, buffers, equilibrium and an organic and biochemistry preview, with short fill-in-the-blank Python calculators.
Cells, membranes, the microscope, DNA and inheritance, microorganisms, blood and the immune system: the biology every lab career builds on.
Core bench skills and instruments: balances, glassware, pipetting, buffers, centrifuges, chromatography, spectrophotometry, calibration, microscopy and aseptic technique.
Keep trustworthy lab records, query LIMS data, run QC with Westgard rules, build calibration curves, estimate uncertainty, and work within SOPs, CAPA and accreditation.
Extract nucleic acids, run PCR and qPCR, read gels, Western blots and ELISAs, compare sequencing methods, and work with sequences and BLAST.
Work like a medical laboratory scientist: accept or reject specimens, read chemistry, hematology, microbiology and blood bank results, call critical values, run daily QC and plan your certification.
Set up and run laboratory experiments for biologists and medical researchers.
Study the chemical and physical processes inside living cells.
Analyze substances and develop new compounds, materials and products.
