The examination syllabus reflects hands-on testing and supervisory laboratory operations. It assesses a technologist's ability to interpret peripheral blood films, resolve blood-banking discrepancies, identify bacterial and parasitic pathogens, evaluate automated analyzer data, and apply statistical quality control rules.

Specialty Module |
Core Topics |
Key Focus Areas & Clinical Scenarios |
|
Clinical Chemistry & Enzymology |
Carbohydrate metabolism, renal panels (BUN, creatinine, clearance), liver enzymes (ALT, AST, ALP, GGT), lipid profiles, cardiac biomarkers (Troponin, CK-MB), and therapeutic drug monitoring. |
Anion gap calculations, resolving hemolyzed or lipemic specimen interferences, diagnosing acid-base disorders from blood gases, and identifying enzymatic kinetic reaction errors. |
|
Hematology & Hemostasis |
Complete blood count (CBC) parameters, red cell indices, manual differential counts, hemoglobinopathies, coagulation cascades, PT/INR, aPTT, and fibrinogen assays. |
Identifying abnormal red and white blood cell morphology on peripheral smears (sickle cells, blasts, toxic granulation), troubleshooting automated platelet clumping, and investigating unexplained prolonged aPTT. |
|
Immunohematology & Blood Banking |
ABO/Rh grouping systems, unexpected antibody screening, crossmatching techniques, Coombs tests (DAT/IAT), and blood component therapy storage standards. |
Resolving ABO discrepancies (subgroups, cold autoantibodies), investigating acute hemolytic transfusion reactions, and managing Rh-negative maternal workups. |
|
Clinical Microbiology & Bacteriology |
Gram-positive and Gram-negative identification pathways, culture media selection, aerobic vs. anaerobic culturing, antimicrobial susceptibility testing (Kirby-Bauer, MIC), and fastidious organisms. |
Differentiating staphylococci and streptococci, interpreting enterobacteriaceae biochemical tests, recognizing extended-spectrum beta-lactamase (ESBL) patterns, and identifying acid-fast bacilli. |
|
Immunology, Serology & Virology |
Antigen-antibody interactions, ELISA, chemiluminescence, autoimmune markers (ANA, RF), hepatitis and HIV serological markers, and viral load measurements. |
Interpreting hepatitis B diagnostic panels (HBsAg, anti-HBs, anti-HBc), troubleshooting prozone/postzone phenomena, and evaluating false-positive rapid screening tests. |
|
Parasitology & Clinical Mycology |
Intestinal protozoa and helminth morphology, blood parasites (Plasmodium species, microfilariae), fungal wet mounts (KOH prep), and opportunistic yeasts/molds. |
Differentiating Entamoeba histolytica from non-pathogenic amoebas, identifying malaria rings and gametocytes on thick and thin blood films, and recognizing Candida and Aspergillus structures. |
|
Urinalysis & Body Fluid Analysis |
Physical and chemical urine examination (reagent strips), microscopic sediment analysis, synovial fluid crystal examination, and cerebrospinal fluid (CSF) cell counts. |
Identifying microscopic casts, dysmorphic RBCs, and crystals, differentiating traumatic taps from true subarachnoid hemorrhage in CSF, and correlating cloudy fluids with sepsis. |
|
Laboratory Safety & Biosafety Standards |
Biosafety levels (BSL-1 through BSL-4), personal protective equipment (PPE), chemical hygiene plans, biohazard waste segregation, and spill containment protocols. |
Immediate response to centrifuge tube breakage, handling suspected risk-group pathogens, standard sharps management, and post-exposure prophylaxis guidelines. |
|
Quality Control & Laboratory Management |
Internal quality control (Levey-Jennings charts, Westgard multirules), external quality assessment (EQA/PT), reference interval validation, and calibration verification. |
Detecting analytical trends and systematic shifts on LJ charts, rejecting out-of-control runs using Westgard rules (1-2s, 1-3s, 2-2s), and tracking pre-analytical specimen rejection rates. |
