A vitamin D lab test is important for women. It measures whether or not your immune system is at risk. If the results are low, a patient is prescribed a supplement. If they are high, then none is prescribed. According to the New York Times, if you’ve had your Vitamin D lab test done by Quest Diagnostics over the last two years, chances are your reading was inaccurately high, meaning you may in fact be deficient even if the results came out adequate.

Vitamin D lab testAccording to Andrew Pollack of the Times:

The company, Quest Diagnostics, has already sent letters to thousands of doctors listing the patients who might have received “questionable” test results and is offering free retests. The company said it had fixed the problems.

The biggest concern right now is to accurately find patients who have had an erroneously high result in their vitamin D lab test. These folks are currently not taking vitamin D supplements when they should be. According to Pollack’s report, the Quest test results have typically been too high, although not in all cases.

Patients need to be aware that there is no standardization for a Vitamin D lab test and that the same sample could yield varying results depending on the lab it is sent to. I suppose the bottom line is to trust your instincts and retest if you feel the results are skewed.
