What tube is used for ethanol?

What is a GREY top blood test for?

Grey top tube Potassium Oxalate. This tube is used primarily for glucose tolerance testing.

What tests are red top tubes used for?

Red top – Tube without gel separator, used mainly for serology and chemistry testing. 10mL Red top tubes are used in Blood Bank for antibody screens.

What is a EDTA tube?

EDTA stands for Ethylenediaminetetraacetic acid. EDTA functions by binding calcium in the blood and keeping the blood from clotting. BD Vacutainer Plus Blood Collection Tubes contain K2EDTA, which is spray-dried to the walls of the tube.

Why is ethanol used in the emulsion test?

The emulsion test is a method to determine the presence of lipids using wet chemistry. The procedure is for the sample to be suspended in ethanol, allowing lipids present to dissolve (lipids are soluble in alcohols).

What test is gray top tube used for?

Lab medicine A blood collection tube containing powdered sodium fluoride and/or potassium oxalate, which inhibits glycolysis; ‘gray tops’ are used for GTT–as glycolysis in the RBCs would cause false-low glucose, for measuring lactate–transported on ice, lactate tolerance. See Glucose tolerance test.

What is a pink top blood test?

Pink. • Spray-coated K2EDTA (plastic) 8 For whole blood hematology determinations. May be used for routine immunohematology testing and blood donor screening.

What is a purple blood test for?

The purple top tube provides blood for infectious disease tests and ascertaining important data such as ABO/Rh (blood type), as well as whether the blood is positive or negative for cytomegalovirus (CMV), HIV, hepatitis, and West Nile virus, to name a few.

What happens if you underfill a tube with blood?

If tubes are underfilled, the blood:anticoagulant ratio may result in hemolysis. Avoid underfilling tubes by having an ample supply of tubes of various capacities.

How much EDTA is in a tube?

The nominal EDTA concentration is 1.8mg EDTA per milliliter of blood.

What is the difference between EDTA and heparin?

EDTA and citrate remove calcium, which most coagulation factors need. Heparin activates antithrombin thereby inhibiting coagulation by inhibiting thrombin. Heparin is used for clinical chemistry tests such as cholesterol, CRP, hormones etc. It interferes with PCR, so if you want to do that use EDTA.

What Colour does ethanol turn when fat is present?
