Which is better sample for glucose estimation?

Hence, serum may be a better sample for blood glucose determination particularly when there is a time delay in the measurement. If appropriate correction is applied, it may actually be a better sample than plasma. Moreover, many clinical analysis procedures require serum rather than plasma.

Which sample tube should be used for routine glucose determination?

Sarstedt serum, lithium-heparin or sodium fluoride/EDTA tubes alone miss the analytical goal for desirable bias. Thus GlucoEXACT tubes allow an accurate glucose determination, which is one of the fundamental criteria for the diagnosis of diabetes [1], [2].

What is added to blood samples collected for glucose analysis?

This study compared the impact of glucose degradation on measured glucose values by examining two different collection methods. For the first method, blood samples were collected in tubes containing sodium fluoride (NaF), a glycolysis inhibitor.

How do you collect blood for glucose test?

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out.

Which is the best way to measure glucose?

The most practical way to measure blood glucose is in the plasma, which is separated immediately after drawing the blood in the presence of an anticoagulant. Most common anticoagulants used are fluoride, Ethylene diamine Tetra acetic acid (EDTA), and heparin (6).

How is blood glucose determined by plasma and serum?

Method: In order to test the relative suitability of plasma and serum for blood glucose determination, fluoride plasma and Ethylene Diamine Tetra Acetic acid (EDTA) plasma were compared with the serum of the same patient. The analyses were carried out within 10 min of drawing the blood and, thereafter, with a gap of 4 hr and 8 hr.

Where can I get a blood glucose test?

Abstract Background: Blood glucose determination is one of the most common clinical diagnostic tests. Often, blood is collected in a field station and analysis is carried out in a remote laboratory.

Which is tube is used for glucose testing?
