Hey, my lab reference range for vitamin B12 is 187 to 883 pg/ml, and my test result is 341 pg/ml. Is this considered normal, or do I have a B12 deficiency? I am 17 years old.

Your B12 level is within the labs normal range but on the lower side. If you experience fatigue or tingling, discuss supplementation with your doctor. A diet rich in B12 or oral supplements might help.

Hi, my blood report says predominantly normocytic normochromic with macrocytes and ovalocytes. What does it mean and what could be the cause? What is its effect and how can it be rectified?

Please see the attached picture of my white tongue. I had oral sex and took HIV ELISA and CMIA tests at 5 weeks, 5 months, and 24 weeks after exposure, all were negative. However, I still have a white coating on my tongue (which I can scrape off in the morning while brushing) and occasional joint pain. I read on the internet that these could be symptoms of HIV, and I have been very worried for months. Are my test results conclusive, or do I need further testing?
