Dating someone with sickle cell

They are ordered routinely as part of newborn screening programs and are mandated by every state in the U. Sickle cell tests may also be ordered along with or following an abnormal complete blood count (CBC) and blood smear to help evaluate someone who has an unexplained hemolytic anemia or who demonstrates symptoms that suggest the presence of sickle cell anemia.

A blood sample is obtained by inserting a needle into a vein in the arm or, for infants, by pricking a heel or finger.

If you do not have your lab report, consult your healthcare provider or the laboratory that performed the test(s) to obtain the reference range. Interpretation of Newborn Hemoglobin Screening Results. Michigan Department of Community Health [On-line information].

Laboratory test results are not meaningful by themselves. ARUP’s Guide to Clinical Laboratory Testing [On-line information].

You may be able to find your test results on your laboratory's website or patient portal. You may have been directed here by your lab's website in order to provide you with background information about the test(s) you had performed.

You will need to return to your lab's website or portal, or contact your healthcare practitioner in order to obtain your test results.

This is a reason why so few reference ranges are provided on this site.

It is important to know that you must use the range supplied by the laboratory that performed your test to evaluate whether your results are "within normal limits." For more information, please read the article Reference Ranges and What They Mean. If the person has one Hb S gene and one other abnormal gene, such as a Hb C gene, then the person will experience some of the same symptoms associated with sickle cell disease. Hb S can form crystals that change the shape of the RBC from a round disc to a characteristic sickle shape. No test preparation is needed; however, testing for diagnosis should not be performed after a recent blood transfusion. Particularly in people with sickle cell disease, the relative amount of Hb S will be measured and followed over the course of treatment, for example, after a blood transfusion to ensure that the hemoglobin S level has been reduced. This altered shape limits the RBC's ability to flow smoothly throughout the blood vessels in the body, limits the hemoglobin's ability to transport oxygen to tissues, and decreases RBC lifespan from 120 days to about 10-20 days.
