Getting tried again is a smart thought, suggests nurture Lucinda K. Watchman, RN, on the off chance that you think you were as of late presented to this irresistible illness.

This ordinary range may not be the same as another lab's, notes the U.S. Nourishment and Drug Administration, so don't be amazed on the off chance that you find that an earlier blood test report fluctuates from more up to date reports — the distinction could be in the lab. 

9. Strange outcomes won't not be because of an ailment. A test result outside the typical scope of expected lab qualities could prompt conclusion of an ailment or confusion. Be that as it may, test results can likewise be irregular for different reasons. In the event that you had a blood glucose test and you ate something before the test, or were drinking liquor the prior night or taking certain solutions, your outcome could be briefly strange. 

10. Botches happen. Despite the fact that misunderstandings of patient blood test tests are uncommon, they do happen, as on account of a HIV patient's example that was exchanged with another person's, coincidentally, as investigated ABC News.
