Which test may require special chain of custody documentation when specimen is collected?
All drug tests, blood alcohol, or any other tests that have medicolegal significance should be accompanied by a chain-of-custody.
When do you perform a GTT?
When you receive a glucose tolerance test, a phlebotomist will draw a sample of your blood through a needle from a vein in your arm after you have fasted for at least eight hours, typically overnight. Then you will drink a sweet drink, and the technician will take more blood samples over the next two to three hours.
Which test requires a specimen with 9 1 ratio?
Venous blood specimens for coagulation assays should be collected into a tube containing 3.2% buffered sodium citrate tube (blue top tube), yielding a whole blood sample with a 9:1 blood to anticoagulant ratio. Inadequate filling of the collection tube will decrease this ratio, and may affect test results.
What does a noninvasive transcutaneous method measure?
Transcutaneous oxygen measurement (TCOM or TcPO2) is a non-invasive method of measuring the oxygen level of the tissue below the skin. Since blood flow is important for wound healing, TCOM is often used to gauge the ability of tissue to effectively heal.
What is the best sample for urine collection?
To collect a urine sample you should:
- label a sterile, screw-top container with your name, date of birth and the date.
- wash your hands.
- start to pee and collect a sample of urine “mid-stream” in the container.
- screw the lid of the container shut.
- wash your hands thoroughly.

What is the normal range for GTT?
gtt normal value The OGTT normal range for after 2 hour test results is between 140 – 199 mg/dL for pre diabetes, 200 mg/dL or greater for diabetes and greater than 153 mg/dL for gestational diabetes.
Which situation can Hemolyze a specimen?
Hemolysis may be due to specimen collection, processing, or transport. Hemolysis may also be due to pathological conditions, such as immune reactions, infections, medications, toxins and poisons, and therapeutic procedures. Frequently, laboratory testing can still be performed on a hemolyzed sample.
What happens if you mix a blood specimen too vigorously?
In theory: (i) when blood tubes are mixed by gentle inversion, the risks of formation of either micro clots, clots or fibrin filaments are limited; and (ii) a vigorous mixing (or shaking) promotes erythrocyte injury or spurious hemolysis [30].
