Vitamin B12 (Cyanocobalamin)

Vitamin B12 (cyanocobalamin) analysis — is a laboratory test that allows you to determine the concentration of this vital trace element in the blood serum. Vitamin B12 plays a key role in the processes of hematopoiesis (synthesis of red blood cells), maintaining the normal functioning of the nervous system and the metabolism of amino acids.

Timely testing for vitamin B12 is necessary for diagnosing macrocytic anemia, assessing neurological status, and monitoring the condition of patients at risk of developing deficiency conditions.

Indications for the analysis:

• Comprehensive diagnostics of the causes of chronic fatigue, weakness and decreased performance.
• Symptoms of nervous system damage: numbness or a feeling of "crawling ants" in the limbs, impaired coordination.
• Signs of anemia (pallor of the skin, shortness of breath, rapid heartbeat), confirmed by a complete blood count.
• Monitoring the condition of people who follow strict diets, veganism or vegetarianism.
• Chronic diseases of the gastrointestinal tract (gastritis, celiac disease, Crohn's disease, condition after gastric resection) that disrupt the absorption of vitamins.
• Long-term use of certain medications (for example, metformin or antacids).

How to properly prepare for the study:

To get accurate results and know your real cyanocobalamin level, follow these preparation rules:

• Biomaterial (venous blood) is strictly on an empty stomach in the morning (after 8–12 hours of fasting). Only clean, still water is allowed to be drunk.
• 24 hours before the test, eliminate fatty foods and alcohol from your diet, and avoid significant physical and emotional stress.
• In consultation with your doctor, stop taking vitamin complexes and supplements containing B vitamins at least 48 hours before donating blood.
• Do not smoke for 1 hour before blood collection.
