Adults contain 1.1 to 1.5 mg of cobalt, which is mainly distributed in the liver, bones, muscles, gastrointestinal tract, kidneys, etc., but eventually accumulates in the bones. The main route of excretion is urine, followed by feces. Cobalt is an important component of vitamin B12. It participates in the process of hematopoiesis through the metabolism of ribonucleic acid and hematopoietic substances through vitamin B12, and plays an important role in hematopoiesis and red blood cell growth.

Basic Information

Specialist classification: inspection classification: biochemical examination

Applicable gender: whether men and women apply fasting: fasting

Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. Normal value

<42.5 nmol/L.

(Note the specific reference value depends on each laboratory.)

Clinical significance

1, elevated in pregnancy poisoning, excessive bleeding, pernicious anemia, cancer anemia, acute leukemia, bone marrow disease.

2, reduced in chronic myelogenous leukemia, lymphogranuloma and so on.

Low results may be diseases: high acute leukemia results may be diseases: chronic granulocyte leukemia considerations

First, the precautions before blood draw

1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results.

2. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results.

3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection.

Second, should pay attention after blood draw

1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma.

2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended.

3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved.

4. If there is localized congestion, use a warm towel after 24 hours to promote absorption.

3. Please inform the doctor about the recent medication and special physiological changes before the test.
