    * Isn't it the reason that every 3 month can be donated because it takes time for the body to replenish the blood in the body and therefore will decrease blood levels in the blood test?

  14. TheAnd monitoring In 09 / 08 / 2019 at 12: 13

    I donated blood this week, and during the routine hemoglobin test in the donation, my level was normal. After a few days, I went for a blood test at a health fund to check vitamin and iron levels, and found that my iron level had dropped sharply since the last test I had done six months ago. Is there a connection between the blood donation I made and the low iron level I discovered after a few days?
