Collection and processing of blood specimens
Specimen type
Anticoagulation
Whole blood
blood cells
plasma
solidification
serum
additive
anticoagulants
Whole blood, plasma, cells
EDTA salt
sodium citrate
heparin
oxalate
coagulant
serum·
For emergency biochemical testing
Separating gel
Quickly obtain serum and plasma, which is convenient for refrigerated storage
Blood collection methods and precautions
capillary blood collection
Part: Fingertips or earlobes, toes or heels of infants and young children
phlebotomy
Median cubital vein, cephalic vein, basilic vein (close to the body surface, straight and thick, no surrounding nerves)
Advantages: Blood samples are easy to transport; different colors, easy to take
Blood collection methods: disinfection, tying tourniquet, puncture, loosening tourniquet, drawing blood, and bleeding.
Types and uses of blood collection tubes
The order of distribution of multi-tube blood collection: blood culture bottle, sodium citrate tube, serum tube, heparin tube, EDTA tube, glycolysis inhibitor tube
arterial blood collection
Radial artery, femoral artery, brachial artery (blood gas analysis)
Shipping and processing of blood specimens
Shipping principles: unique identification, biosecurity, timely delivery
Signing and rejecting:
Pretreatment (centrifugation): plasma---immediate centrifugation, serum---centrifuge after the blood clot has shrunk (37°C)
Storage: Blood routine---normal temperature, biochemical and immunological testing---stored at 4℃ for one week
Post-detection processing: centralized processing after disinfection
Full quality assurance of blood specimens
Biosafety: patients, medical workers, environment
Patient status: physiological status, diet, medications (doctor’s note)
Blood collection operation: time, location, body position, use of tourniquet, infusion, hemolysis
Send for inspection immediately
