QuestionAnswer
Point provides smooth entry into skin with minimum of pain.
Bevel ANGLE that eases into skin preventing coring of tissue.
Shaft the length and gauge of the needle.
Gauge the DIAMETER of the needle's lumen
Lumen the HOLLOW TUBE within the shaft
Lumen size the SMALLER the gauge number, the LARGER the lumen
The LARGEST diameter needles routinely used in phlebotomy are 16 Gauge
Gauge used in BLOOD BANK 16-18 Gauge
The SMALLEST diameter needles routinely used in phlebotomy are 23 Gauge
Typical routine adult needle size is 21 Gauge
Hub where the needle attaches to the holder
The most common size needle used for a SYRINGE 22 Gauge, 1 inch long.
Winged infusion set Butterfly
The most common size needle for the Butterfly/Winged Infusion set 23 Gauge, 3/4 inch long
Whole Blood is mixed with anticoagulant so it will not clot
Serum Fluid remaining after clot has formed.
How long does it take for a clot to form (without activators)? 30-60 minutes
Does SERUM contain FIBRINOGEN? Serum DOES NOT CONTAIN FIBRINOGEN OR CLOTTING FACTORS, because it has been used in the clot. Not good for coagulation studies.
Plasma Fluid portion of the blood. CONTAINS FIBRINOGEN AND CLOTTING FACTORS. Anticoagulant has been used
Anticoagulants that BIND CALCIUM EDTA, Sodium Citrate, Potassium Oxalate, and SPS.
Anticoagulants that prevent the conversion of PROTHROMBIN TO THROMBIN heparin (sodium, lithium or ammonium heparin)
Polymer gel thixotropic gel, inert, synthetic substance with density between that of cells an blood serum or plasma.
Yellow Sterile SPS-to recover microorganisms in a blood infection.
Light Blue SODIUM CITRATE-for coagulation studies. Fill tube completely for 9/1 ratio.
Red (plastic or glass) PLAIN - Chemistry/Serology/Blood Bank. Plastic-invert 5 times. 60 minutes to clot.
Lavender EDTA - for CBC, Sed Rate
Pearl Polymer gel with EDTA - for viral loads
Gold BD Hemogard Closure or Red Grey Clot activators with Polymer Gel = SST - for most chemistry tests Invert 5 times, clots requires at least 30 minutes.
Gray Sodium Fluoride &/or Potassium Oxalate - for FBS, GTT, Lactic Acid and blood ALCOHOL
Iodoacetate Preserves blood glucose for 24 hours
Sodium fluuoride Preserves blood glucose for 3 days.
Black for Sed Rate, although a Lavender tube is usually used.
Green Heparin - Stat Chemistry, ammonia, electrolytes, ABG's
Light Green Heparin + Polymer gel - Stat Potassium
Orange BD Hemogard Closure or Yellow Gray Thrombin - Stat Chemistry 5 MIN. CLOTTING TIME!
