A medical laboratory technician (MLT) runs the routine tests that doctors rely on to diagnose and treat patients: blood counts, chemistry panels, urinalysis, blood typing, and cultures. Most US employers want an associate degree from a NAACLS-accredited program plus the ASCP MLT certification. A few states (such as California, Florida, Nevada, and New York) also require a state license or personnel permit, so check yours early. This roadmap teaches you the why behind each test, so you can spot a bad result instead of just reporting it. You build science and math foundations first, then bench s

Stage 1 of 4 · about 12 weeks
Learn the basic biology, chemistry, and lab math behind every test: cells, blood, solutions and dilutions, the metric system, lab safety (OSHA bloodborne pathogens, PPE), and how to read a procedure carefully. Practice dilution and molarity problems until they feel routine.
Lab safety and bloodborne pathogen basics
Every sample you touch could carry infection. Safety habits protect you, your coworkers, and the patient's sample. Programs and employers expect you to know them before your first day.
Metric system, units, and measurement
Every result you report has a unit, and a wrong unit can harm a patient. Labs run on SI and metric units, so converting quickly and accurately is a daily skill.
Chemistry for the lab: moles, molarity, pH, and solutions
Reagents, calibrators, and controls are solutions. You can't prepare or trust them without knowing what concentration means. Chemistry is also the base for clinical chemistry later.
Dilutions and lab math
Patient samples are often too concentrated for an analyzer, and reagents are made from stocks. Dilution errors give wrong results, so this must feel automatic.
Cell and blood biology basics
Every test you will run looks at cells or the fluid around them. Knowing what normal looks like lets you notice what is abnormal.
Reading and following a procedure precisely
Core lab work is following a written standard operating procedure (SOP) exactly, noticing when something is off, and documenting it. O*NET ranks reading comprehension and critical thinking at the top of this job.
