Speaking of EDTA potassium, the editor remembered when he went to the hospital for a physical examination before, he met a child in the front row and asked his mother, "Why are there water droplets in the purple tube. Seeing Baoma's bewildered expression, I couldn't help but poke in a mouthful. The small water droplets inside were EDTA dipotassium, which can prevent the extracted blood from clotting.
EDTA K2
In order for everyone to apply what they have learned, today I will introduce EDTA potassium, which can chelate with calcium ions in the blood and have a blood anticoagulant effect. The Chinese name of EDTA is actually Ethylenediaminetetraacetic acid, which is called EDTA directly because it is too long and tongue twister.
EDTA dipotassium is a calcium chelating agent that appears as a white amorphous powder, odorless, and soluble in water. It is generally used for complexing metal ions and separating metals, and is used in blood Anticoagulant, detergent, liquid soap, shampoo and other fields. EDTA potassium is installed in the purple cap's blood collection tube, so the purple blood collection tube is also called an anticoagulant tube. It is used to complete the routine blood test, blood ammonia, blood type and other items that people often do, and it is also used to monitor Glycated hemoglobin in patients with diabetes!
In fact, EDTA potassium also has a "brother", three potassium. The appearance of the two is very similar, but the powder of three potassium will be more delicate, and the effect of dissolving in water is better. Although it is difficult to distinguish the two with the naked eye, the Molecular formula is different after all. It is one more potassium ion than dipotassium. It is not widely used as dipotassium, and is basically only used for blood anticoagulation.
So when going to the hospital to collect blood, don't look at the colorful hats that collect blood vessels. The colors you use are different from those used by others. This is not something that the nurse sister casually picked up. The additives in the blood collection tubes of different colors are also different, which can be roughly divided into Anticoagulant, coagulant accelerator and separating gel, and the corresponding inspection items are also different.
