Are lab test results always right?

While they do have to meet very high standards, they can be wrong sometimes. For example, you might get a false positive (the results say you have the condition you were tested for, but you really dont) or a false negative (the results say you don’t have a condition, but you really do).

Lab test failures contribute to delayed or wrong diagnoses and unnecessary costs and care. For context, a 2014 study estimated that diagnostic errors happen about 12 million times per year in U.S. outpatients. This represents 1 in 20 adults. In case you think your blood test result doesn't make any sense, we recommend that you do the test again from HealthLabs as they perform testing using verified methods and they test blood only in the best CLIA certified labs. You won't need a doctor's referral or insurance.
