What else can I help you with?
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 blood tube for FBG?
Gray top tube is typically used for fasting blood glucose (FBG) testing.
Is potassium oxalate added to the gray vaccum tube?
No, potassium oxalate is not added to the gray vacuum tube. The gray-top tube typically contains an anticoagulant such as potassium oxalate and sodium fluoride for glucose testing.
Color tube is used for glucose test?
The color tube used for a glucose test is typically a gray-top tube, which contains sodium fluoride as a preservative and an anticoagulant. The sodium fluoride helps preserve glucose levels in the blood sample by inhibiting glycolysis, while the anticoagulant prevents clotting. This tube is commonly used for glucose testing to ensure accurate and reliable results.
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 blood collection tube is sodium fluoride in?
Sodium fluoride is typically found in gray-top blood collection tubes, which are used for glucose testing because sodium fluoride acts as a glycolysis inhibitor to preserve the specimen for accurate glucose measurements.
Which color tube contains sodium fluoride as an additive?
The color tube that contains sodium fluoride as an additive is typically gray. Sodium fluoride is added to inhibit glycolysis in blood samples for glucose testing.
What color tube for glucose tolerance test?
A gray tube is typically used for a glucose tolerance test. This tube contains sodium fluoride as an additive to preserve glucose levels in the blood sample.
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 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 color tube to test for glucose tolerance?
The tube used to test for glucose tolerance is typically a gray-top tube. This tube contains a preservative that helps prevent changes in glucose levels after the blood is drawn, ensuring accurate test results.
What color tube for amylase?
A gray tube or plain red-top tube can be used for amylase testing. It is important to follow the specific specimen collection requirements of the laboratory where the testing will be performed.
