Study Notes
Laboratory Samples
- Laboratory samples can be classified into two categories: blood and non-blood samples.
- Blood samples can be further divided into arterial, venipuncture, and capillary samples.
Blood Collection Methods
- Syringe method: uses a slip tip or luer lock syringe, available in various capacities (3, 5, 10, 20, 60 cc), and needles with different gauges and lengths.
- Vacutainer method: uses a double-sided needle and a vacuum-dependent system.
Blood Tubes
- Anticoagulated blood tubes: used for plasma samples, available in different colors, each with specific anticoagulants and additives.
- Gray top: contains sodium fluoride and potassium oxalate, used for glucose tests.
- Purple top: contains EDTA, used for CBC, ESR, and sickle cell tests.
- Blue top: contains sodium citrate, used for PT, PTT, and INR tests.
- Green top: contains lithium heparin, used for chemistry tests.
- Non-anticoagulated blood tubes: used for serum samples, available in red or yellow (SST) tubes.
- Red or yellow top: used for lipid profile, renal function, liver function, and other tests.
Common Tests and Departments
- Clinical Chemistry: glucose, lipid profile, renal function, liver function, and other tests.
- Hematology: CBC, ESR, sickle cell test, and blood type.
- Coagulation/Hematology/Clinical Chemistry: PT, PTT, INR, D-DIMER tests.
- Immunology: ELISA, CLIA, microbead, and IF tests for various analytes.
Non-Blood Samples
- Urine: used for urinalysis, 24-hour urine analysis, and microscopy.
- Stool: used for microscopy, analysis, and count.
- Sputum: used for analysis and count.
- Semen: used for analysis and count.
- Swabs: used for throat, wound, and rectal swab analysis.
- Fluids: used for synovial, pleural, CSF, and other fluid analysis.
- Cytology: used for histology and cytology tests.
- Histology: used for tissue analysis, typically with 10% formalin.
