Green top tube

Blood Tube Draw Volume

Min 50% draw volume  

Minimum Volume to Submit for Testing

Transportation Needs

 Deliver specimen to laboratory within 1 hour of collection if unspun. If not possible see "storage Requirements". 

Storage Requirements

Sample tubes should be centrifuged within 2 hours of collection 

Gold tops are stable in original tubes for 7 days DO NOT ALIQUOT

Aliquot Red tops

See Causes of Rejection for temperature requirements.

Causes for Rejection

Mislabeled or unlabeled specimen
Less than 50% draw for Vacutainer tubes
 >7 days refrigerated 
> 24 hours room temperature
> 1 year Frozen

Hemolysis > 500 mg/dL HgB
Lipemia > 500 mg/dL Trig
Bilirubin > 12 mg/dL Bili

EDTA, NaF, Citrate, Oxalate

Limitations

Bacterial contamination of the specimen may cause increased lipase values

Hemoglobin at a test concentration of 500 mg/dL [0.31 mmol/L] increases the lipase activity by 30 U/L at a lipase level of 143 U/L. Hemoglobin at a test concentration of 500 mg/dL [0.31 mmol/L] has less than 10% interference at lipase levels greater than 300 U/L.

EDTA, potassium oxalate, sodium fluoride and citrate have been shown to inhibit lipase results and should not be used.

Additional Information

Contraindications:

Lipase is increased in approximately 50% of patients with chronic renal failure. Serum lipase increases with hemodialysis. Therefore, predialysis blood samples are recommended for lipase movement.
