Sodium Fluoride/Potassium Oxalate (NaF/K Oxalate) tubes (vacutainers), also sometimes referred to as gray-top tubes due to their color, are specifically designed for tests that require preserved levels of certain analytes, particularly blood glucose (sugar).

tube는 실리카결정(silica particle)으로 코팅되어 있어, 혈액이 들어가면 응고를 촉진시키게 된다. (혈소판에 달라붙어 thrombin의 형성을 촉진시키고, 결국 fibrin 형성을 촉진하여 blood clot을 만들어 낸다.)

Nidovac™ Na-Fluoride Tubes are available globally acceptable combination for NaF+EDTA, as this combination is preferred due better stability and lesser chances of Plasma Haemolysis as compared to the Oxalate version.

To compare glucose values obtained using sodium flouride (NaF) tubes and serum separation tubes (SST) in a tertiary care hospital laboratory setting. This study was conducted at the Clinical Biochemistry Laboratory, Royal Hospital, Oman.

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.

These VACUETTE® tubes contain sodium fluoride as a stabilizer and the additive potassium oxalate as an anticoagulant. IFU Instructions for Use / PDF, 223 KB / FOR USA ONLY!

This study aimed to analyze the differences in blood glucose levels between routine serum tubes and sodium fluoride (NaF) tubes over time intervals. Methods: The study included 50 participants from whom blood was collected in both serum and NaF tubes.

Nov 10, 2023 · Sodium fluoride potassium oxalate tubes, called NaF/KOx tubes, are indispensable clinical chemistry and haematology tools. These tubes are pivotal in preserving blood samples for various diagnostic tests, ensuring accurate results.

Vacutainer Sodium Fluoride tubes are used to collect blood samples for glucose determinations. They contain sodium fluoride and potassium oxalate or Na2EDTA. These chemicals preserve the glucose levels in blood samples, so test results are more …

Dec 1, 2015 · Most recent studies on glucose stabilities confirm that the sodium fluoride/potassium oxalate (NaF/KOx) tube is far from the gold standard.
