A glucose specimen was forgotten in a phlebotomist's tray. it was discovered 3 hours later?
If a glucose specimen is left at room temperature for 3 hours, it may be subject to glycolysis, where red blood cells consume glucose, potentially leading to falsely low glucose results. It is generally recommended to process glucose samples within 1-2 hours of collection to ensure accuracy. Therefore, the specimen should not be used for testing, and a new sample should be collected for reliable results.

What glucose tolerance test is an example of a specimen?
A1c
What specimen required for GTT test?
The Glucose Tolerance Test (GTT) requires a blood specimen, typically collected from a vein. In some cases, a urine specimen may also be collected to assess glucose levels in urine. The test usually begins with a fasting blood sample, followed by the patient consuming a glucose-rich drink, with additional blood samples taken at specified intervals to monitor how the body processes the glucose.
What is preferred specimen for glucose analysis?
For glucose analysis, the preferred specimen is typically blood. This could be collected either from a vein (venous blood) or a fingertip prick (capillary blood). Blood glucose levels are commonly used to monitor and manage conditions such as diabetes.
What is the purpose of an antiglycolytic agent?
Its purpose is to inhibit the metabolism of glucose by cells in a specimen of blood.
How was glucose discovered?
Glucose was first discovered in the early 19th century by German chemist Andreas Sigismund Marggraf and further analyzed by French chemist Louis Pasteur. It was originally isolated from grapes and termed "grape sugar" due to its abundance in fruits.
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.
What is a 2 hr postprandial specimen?
A 2-hour postprandial specimen refers to a blood sample taken two hours after a meal. This test is often used to assess how the body processes glucose and is particularly important in diagnosing diabetes or insulin resistance. The results can help evaluate how well the body manages blood sugar levels after eating. Typically, healthcare providers recommend this test to monitor glucose levels in patients with diabetes or those at risk.
What tube for Gtt?
For glucose tolerance tests (GTT), a gray-top tube is typically used. This tube contains sodium fluoride and potassium oxalate, which help preserve glucose levels and prevent glycolysis during the specimen collection and transport process. It is important to follow specific protocols for collection and handling to ensure accurate test results.
What is the carbohydrate that is found in abundance in mammalian blood?
Glucose
What is a combination of lab tests that are performed on a urine specimen called?
A combination of lab tests performed on a urine specimen is called a "urinalysis." This comprehensive evaluation typically includes physical, chemical, and microscopic examinations to assess various parameters, such as pH, protein levels, glucose, and the presence of cells or bacteria. Urinalysis is commonly used to diagnose conditions like urinary tract infections, kidney disease, and diabetes.
Who discovered that the liver converts glucose into glycogen and stores it?
The discovery that the liver converts glucose into glycogen and stores it is attributed to the work of several scientists, but key contributions came from Claude Bernard in the 19th century. Bernard's experiments demonstrated the role of the liver in glucose metabolism, particularly its ability to produce and store glycogen. His findings laid the foundation for understanding glycogen's role in energy storage and regulation in the body.
Is Glucose a component of all three dietary disaccharides?
No, glucose is a component of two dietary disaccharides: maltose (glucose + glucose) and lactose (glucose + galactose). Sucrose (glucose + fructose) does not contain glucose.
