5. Hematology
Hematology involves analysis of blood and its components—CBCs, differentials, cell morphology, coagulation testing—to detect and monitor disease.
Why It's Important
It guides diagnosis and management for anemia, infections, coagulopathies, hemoglobinopathies, and hematologic malignancies.
How to Improve Hematology Skills
Treat analyzers right: Daily QC, maintenance, and calibration verification; troubleshoot flags with reflex tests.
Keep smears sharp: Uniform thickness, proper staining, and systematic review patterns for accurate diffs.
Validate reflexes: Clear rules for manual diffs, retics, ESR, or peripheral smear review based on instrument flags.
Proficiency and QC: Regular proficiency testing, delta checks, and peer comparisons to catch drift early.
Close the loop: Correlate results with clinical info and previous values; question what doesn’t fit.

6. Biochemistry
Clinical biochemistry measures analytes in blood, urine, and other fluids—electrolytes, enzymes, metabolites, proteins—to illuminate physiology and pathology.
Why It's Important
It supports fast, data-driven care in emergencies, chronic disease management, and therapy monitoring.
How to Improve Biochemistry Skills
Own pre-analytics: Correct tubes, prompt processing, proper storage; hemolysis and lipemia checks every time.
Strengthen QC: Multi-level controls, Westgard rules, lot-to-lot bridging, and trending with action limits.
Validate methods: Linearity, carryover, interference studies, and reference interval verification before live use.
Use data smartly: Middleware rules, auto-verification criteria, and delta checks to reduce manual errors.
Safety and sustainability: Chemical handling, waste logs, and spill response—all routine, all documented.

7. Spectrophotometry
Spectrophotometry quantifies analytes by measuring absorbance at defined wavelengths—central to many chemistry and enzyme assays.
Why It's Important
It provides precise, reproducible quantitation for biomarkers, drugs, and metabolites when calibrated and controlled well.
How to Improve Spectrophotometry Skills
Verify wavelengths: Use certified standards or internal checks to confirm wavelength accuracy and stray light limits.
Mind cuvettes and wells: Clean, scratch-free optics and proper pathlength; consistent plate type and positioning.
