Specimen Collection and Preparation

 

 

Patient Preparation

Verify patient identification by having patient, parent or guardian state full name and date fo birth. Photo identification is mandatory for chain of custody drug screening.

 

Specimen Collection

The phlebotomist may collect blood samples by venipuncture or capillary draw. The doctor, a physician office employee, the patient or the patient's guardian is responsible for collecting other specimen types.

 

 

Plasma

Draw blood in the designated color-coded tube. Immediately mix the blood by inverting gently 10-12 times. Within 30 minutes, separate the plasma by centrifugation for 10 minutes. Transfer to properly labeled, plastic vial. The vial must have sample type written on the container.

 

 

Serum

Draw blood in tube containing no anticoagulants. To obtain 4 mL serum, draw at least a full 10 mL tube. If serum separator tube is drawn, invert tube 5 times. Allow blood to clot for 30 minutes. Centrifuge for 10 minutes. If the blood was drawn in a plain red tube, transfer serum to plastic vial. The vial must have sample type written on the container.

 

 

Urine, Random 

If random urine is required, collect a clean-catch urine in a clean container with leak-proof lid.

 

 

Urine, Timed

Timed urine collection is required for quantitative tests. Accurate test results depend on proper collection and preservative of timed urine specimens. On the day of collection, discard the first voided urine and begin timing the collection. Refrigerate urine during collection. Collect all urine for the time span designated. Include the sample collected at the end of the time span. Record collection duration.

 

 

Whole Blood

Draw blood in the designated anti-coagulant color-coded tube. Immediately mix blood by inverting the tube gently 10 to 12 times. Unless otherwise specified, submit tube unopened.
