PocTell® Glucose Gray tubes, often called gray top tubes or blood sugar tubes, are specialized containers used in medical environments to collect blood samples for glucose level measurement. They play a crucial role, especially in diagnosing and monitoring diabetes. These tubes are easily recognizable by their gray colored caps.
Composition and Function of Additives
PocTell® Glucose gray top tube contains the anticoagulant fluoride oxalate. This substance serves two main purposes: it preserves the blood sample, preventing clotting, and may also have additives that inhibit glucose breakdown. This ensures that the glucose levels measured are accurate, which is vital for proper diagnosis and management of metabolic conditions.

Features
Material
PocTell® Glucose Gray tubes can be made of either glass or PET plastic. Glass tubes are a common choice for laboratory settings due to their stability and compatibility with various laboratory equipment. On the other hand, plastic tubes (PET) are more suitable for clinical and point - of - care testing because they are lighter, less likely to break, and easier to handle in these fast - paced environments.
Size and Volume
These tubes come in a range of sizes, with volumes typically from 1 ml to 10 ml. The selection of the appropriate size depends on the amount of blood sample required for a particular test. For example, some glucose tests may only need a small sample, while others, like more comprehensive metabolic studies, might require a larger volume.
Additives Variety
In addition to fluoride oxalate, some glucose tubes may contain other additives such as sodium fluoride or sodium citrate. These additives work together to preserve the blood sample and prevent glucose degradation until the sample can be analyzed. This ensures that the glucose level measured is a true reflection of the patient's condition at the time of sample collection.
