24 mar 2024 · The gray top tube contains potassium oxalate/sodium fluoride, specifically for glucose and lactate testing. These additives keep glucose levels stable until they can be analyzed, useful for tests like: Fasting Blood Sugar (FBS) Glucose Tolerance Test (GTT) Lactic Acid; Blood Alcohol Concentration (BAC) Royal Blue Top Tube. Royal blue top tubes ...
17 lip 2023 · A blood gas test measures the amount of oxygen and carbon dioxide in the blood. It may also be used to determine the pH of the blood, or how acidic it is. The test is commonly known as a...
16 lis 2022 · A blood glucose test measures the level of glucose (sugar) in your blood. The test can involve a finger prick or a blood draw from your vein. Healthcare providers most commonly use blood glucose tests to screen for Type 2 diabetes, which is a common condition.
Chemistry. [edit] Test tubes intended for general chemical work are usually made of glass, for its relative resistance to heat. Tubes made from expansion-resistant glasses, mostly borosilicate glass or fused quartz, can withstand high temperatures up to several hundred degrees Celsius.
10 paź 2015 · Capillary blood sampling is a medical procedure aimed at assisting in patient diagnosis, management and treatment, and is increasingly used worldwide, in part because of the increasing availability of point-of-care testing. It is also frequently used to obtain small blood volumes for laboratory testing because it minimizes pain.
In order to determine the most suitable blood collection tube for this purpose we have compared different tubes: sodium fluoride, lithium heparin, sodium fluoride/citrate buffer containing tubes and serum with clot activator tube for the measurement of glucose when the tube has been kept at room temperature (RT) for up to 4 h. Methods.
Citrate tubes have been suggested as the preferred tube type by many institutions. Greiner has introduced a glucose-specific tube (Glucomedics) containing NaF/KOx, citrate, and EDTA to minimise glycolysis. The aim was to determine which tube would be the most suitable for accurate glucose estimation in a routine laboratory setting.
