CBC test is done by pricking or collecting venous blood. The test shows the nutritional status of the micronutrient blood levels of vitamins and minerals in the body. If the levels are too low, then it indicates the need of supplements which are crucial for your health.

Hello, my dad (age 50 years) experiences extreme anger. Due to this, we conducted a complete profile test including blood test, vitamin test, and urine test before and after food, but we were not satisfied. Vitamin B12 estimation shows serum B12 of 217. Please suggest which homeopathic medicine to take to control the vitamin B12?

Answered by Apollo Doctors

Hi doctor, earlier I had updated my blood report and you suggested me to take multivitamins with minerals. I am again updating my blood report. I sometimes feel fatigue and sudden dizziness but otherwise I am eating well, sleeping, and working normally. Please suggest some multivitamins that I can take. Thank you.
