Quest Confirms It Sent Out Botched Medical Test Results
Madison, New Jersey based Quest Diagnostics, the largest medical diagnostic facility in the country has admitted that it sent out a large number of erroneous Vitamin D test results to doctors and patients in 2008. The company launched an investigation into the matter in June when doctors from around the country began questioning the validity of some of the test results that they had received. The announcement comes after a probe confirmed that errors had indeed been made with an unspecified number of Vitamin D blood tests that the company had conducted last year.
The company hasn't confirmed how many patients may have been affected by the inaccurate test results nor has it admitted the number of laboratories that were involved in these messed up results. According to industry watchers however, the number is possibly in the thousands. The company has faced problems with Vitamin D analysis testing of the blood before, and had changed its test design from an earlier FDA approved one to a new design. However, the new test design has problems of its own, especially when used to test large volumes.
And volumes of Vitamin D tests have increased dramatically Quest. Recent studies have now linked Vitamin D to the prevention of a number of diseases including cancer, diseases of the auto immune system, and heart disease, although these findings have been debated by medical experts. Besides, Vitamin D has for decades been recognized for its bone strengthening abilities.
The inaccuracy of the results could have led to two kinds of prescription errors, experts say - either the test results may be erroneously too low, in which case a patient who doesn't really need any additional supplements may end up developing an over dosage reaction to Vitamin D, or the results could show a higher reading that ensures that patients don’t receive the strength of dosage they require. At least one doctor in New York City has confirmed that one of his patients developed a toxic level of Vitamin D in the blood as the result of an overdose.
Toxicity of Vitamin Dcan be seen in minor symptoms, like nausea, vomiting and constipation, but its major effects can be seen in the form of increased levels of calcium in the blood, disorientation and abnormal heart rhythm. Excess calcium can be deposited in the kidneys, increasing the risk of kidney stones.
The question doctors and Monmouth County medical malpractice lawyers are asking is why the company took so long to admit that there had been inaccuracies in its results, when these slip-ups had first been brought to its attention in 2007.
