Medical Laboratory Techniques: A Comprehensive Guide
Medical Laboratory Techniques involve the analysis of biological specimens (blood, tissue, fluids) to diagnose diseases, monitor treatments, and ensure patient health. Lab technicians and technologists play a critical behind-the-scenes role in healthcare.
1. Key Areas of Medical Laboratory Science
| Department | What It Analyzes | Common Tests |
|---|---|---|
| Hematology | Blood cells | CBC, Hemoglobin, Coagulation tests |
| Clinical Chemistry | Body fluids (glucose, enzymes) | Lipid panel, Liver/kidney function tests |
| Microbiology | Bacteria, viruses, fungi | Cultures, Antibiotic sensitivity tests |
| Immunology/Serology | Immune system responses | HIV, Hepatitis, COVID-19 antibody tests |
| Histopathology | Tissue samples (biopsies) | Cancer detection, Autopsy analysis |
| Molecular Diagnostics | DNA/RNA (genetic testing) | PCR, Genetic disorders, Forensic analysis |
2. Roles in Medical Laboratory Science
| Job Title | Responsibilities | Education Required |
|---|---|---|
| Medical Lab Technician (MLT) | Performs routine tests under supervision | Associate degree + certification (e.g., ASCP) |
| Medical Lab Technologist (MLS/MT) | Complex testing, supervises MLTs | Bachelor’s degree + certification |
| Histotechnologist (HTL) | Prepares tissue samples for pathologists | Bachelor’s + HTL certification |
| Phlebotomist | Collects blood samples | Short-term certification program |
| Lab Manager/Supervisor | Oversees lab operations, quality control | Bachelor’s/Master’s + experience |
