What tube is an ethanol level drawn?
An ethanol level is typically drawn in a gray-top tube containing potassium oxalate and sodium fluoride as preservatives.
Isomers of trisoxalatochromate ion?
The trisoxalatochromate ion has two isomers: fac-trisoxalatochromate and mer-trisoxalatochromate. In fac-isomer, the oxalate ligands are arranged in a facial manner, whereas in the mer-isomer, the oxalate ligands are arranged in a meridional manner around the chromium central atom.
What tube contains an antiglycolytic agent?
The gray-topped tube, also known as a fluoride tube, contains an antiglycolytic agent such as potassium oxalate or sodium fluoride. This tube is used to preserve glucose levels in a blood sample by inhibiting glycolysis, which is the breakdown of glucose by cells.
What is the best tube for collecting an ethanol specimen?
A gray-top tube containing sodium fluoride (preservative) and potassium oxalate (anticoagulant) is commonly used for collecting ethanol specimens in forensic and toxicology testing.
What color is the tube top used for a glucose draw?
The tube top used for a glucose draw is typically gray. This tube contains sodium fluoride as a preservative and potassium oxalate as an anticoagulant to prevent the breakdown of glucose in the sample.

What does a gray top tube contain?
A gray top tube typically contains potassium oxalate and sodium fluoride as an anticoagulant/preservative for glucose testing. This tube is used for collecting blood samples for glucose testing and helps prevent glycolysis (breakdown of glucose).
What color tubes prevent glycolysis?
Gray tubes containing sodium fluoride and potassium oxalate are commonly used to prevent glycolysis by inhibiting the enzymes responsible for breaking down glucose in the blood sample. These additives help preserve glucose levels for accurate testing in the laboratory.
What is the best tube for collecting an ethanol specimen?
A gray-top tube containing sodium fluoride (preservative) and potassium oxalate (anticoagulant) is commonly used for collecting ethanol specimens in forensic and toxicology testing.
What color is the tube top used for a glucose draw?
The tube top used for a glucose draw is typically gray. This tube contains sodium fluoride as a preservative and potassium oxalate as an anticoagulant to prevent the breakdown of glucose in the sample.
What additive does the gray tube in the order of draw have?
Order of draw is Yellow addictive is SPS blood culture invert 8-10 times. Light blue addictive is Sodium Citrate invert 3-4 times. Red addictive No clotting invert 5-8 times. Serum addictive Silica invert 5-8 times. Green addictive heparin invert 8-10 times. Lavender addictive EDTA invert 8-10 times. Last is Gray addictive Potassium invert 8-10 times
What is gray top tube used for in lab draws?
A gray top tube is typically used for collecting blood samples for glucose testing or other tests that require preservation of glucose levels. The tube contains sodium fluoride and potassium oxalate as anticoagulants and preservatives to prevent glycolysis (breakdown of glucose) in the blood sample.
What phlebotomy tubes do not get spun in the centrifuge?
Gray top tubes with sodium fluoride/potassium oxalate additive should not be spun in the centrifuge as it can alter test results by causing hemolysis. These tubes are usually used for glucose testing and need to be kept upright to prevent mixing with cells.
What color tube do you use when testing for alcohol?
When testing for blood alcohol content (BAC), a gray top tube with potassium oxalate and sodium fluoride is typically used to prevent alcohol metabolism in the sample. This tube helps ensure accurate BAC results by stabilizing alcohol levels during transportation and storage.
What color tube is used to draw serum osmolality?
A gray-top tube with sodium fluoride/potassium oxalate is typically used to draw a sample for serum osmolality testing. This tube is preferred because it inhibits glycolysis, which can affect osmolality measurements.
