SPECIMEN TYPE AND REQUEST FORM

In general, 5 to10 ml of fresh venous blood sample is appropriate for chemical analysis. Collect blood specimen and add to the correct collection tubes. Cap tight. Mix gently for 10 to 20 times by inverting/ rotating the tubes. Send to clinical laboratory immediately without delay. Always dispatch sample together with the respective request form. Specimens received without request forms will not be entertained. Keep all sample at 4oC during transport.

BLOOD GASES and ASTRUP

THERAPEUTIC DRUG MONITORING

Please specific time of sampling on the request form clearly. Sometimes 2 samples are required (i.e. one for Peak level and another for Trough level)
