Study Notes
Laboratory Samples
- Blood samples can be collected through arterial puncture, venipuncture, or capillary puncture
- Non-blood samples include stool, urine, sputum, semen, and other bodily fluids
Blood Collection Methods
- Syringe method: uses a slip tip or Luer lock syringe with needles of varying gauges and lengths
- Vacutainer method: uses a double-sided needle and a vacuum-dependent system
Blood Tubes
- Anti-coagulated tubes:
- Gray top (sodium fluoride/potassium oxalate): used for glucose tests
- Purple top (EDTA): used for CBC, ESR, and other hematology tests
- Blue top (sodium citrate): used for coagulation tests (PT, PTT, INR, D-dimer)
- Green top (lithium heparin): used for chemistry tests (electrolytes, enzymes, etc.)
- Non-anti-coagulated tubes:
- Red or yellow (SST) top: used for lipid profiles, renal function tests, and liver function tests
Common Laboratory Tests
- Clinical Chemistry:
- Glucose (FBS, RBS, FBS & 2HRPP, GTT)
- Lipid profile (cholesterol, triglycerides, HDL)
- Renal function tests (BUN, creatinine, uric acid, electrolytes)
- Liver function tests (SGOT, SGPT, ALK PHOS, GGT, bilirubin, etc.)
- Hematology:
- CBC/FBC
- ESR
- Sickle cell test
- Hemoglobin
- Immunology:
- HIV
- Hepatitis A, B, and C
- Dengue fever
- Toxoplasmosis
- Rubella
- Measles
