Study Notes
Blood Samples
- Arterial blood samples can be collected via P.Venipuncture
- Capillary blood samples can be collected via Direct or Indirect methods
- Specialized blood samples have a higher risk and require more invasive procedures
- POCT (Point of Care Testing) blood samples are less invasive and safer
Blood Collection Methods
- Syringe Method: uses slip tip or Luer Lock syringes with various capacities (3, 5, 10, 20, 60 CC)
- Syringe Method: uses needles with different gauges (18, 20, 21, 22, 23, 25) and lengths (1 inch or 1.5 inch)
- Vacutainer Method: uses a double-sided needle and vacuum dependent system
- Vacutainer Method: may result in potentially adequate volumes, but has a high incidence of inadequate volumes
Blood Tubes
- Anti-coagulated blood tubes (Plasma): Gray, Purple, Blue, Green (and others)
- Non-anti-coagulated blood tubes (Serum): Red, Yellow (SST)
Non-Blood Samples
- Urine samples: used for Urinalysis, m/c/s, and 24hr analysis
- Stool samples: used for OBR, OCP, M/C/S, and MAU analysis
- Sputum samples: used for microbiological analysis
- Semen samples: used for microbiological analysis
- Swab samples: used for microbiological analysis (hvs, throat, wound, rectal, etc.)
- Fluid samples: used for analysis (synovial, pleural, CSF, etc.)
- Histology samples: require 10% Formalin
- Cytology samples: require specific preparation and analysis
