Through a Direct Access Laboratory
As with home testing, direct access testing (DAT) has been growing in popularity over the past few years. Currently, 34 states permit consumers to order their own lab tests – without a medical order from their health care provider. Also known as patient authorized testing, DAT is a reflection of Americans' focus on health and preventive medicine, offering the opportunity for patients to take a more active role in their own health care.
In some respects, direct access testing has been around for some time. Over-the-counter home tests are a type of DAT since they do not require a prescription and can be bought and used at the consumer’s discretion. Now, the trend has expanded to include laboratories offering clinical tests at the patient’s request. In retail centers in Colorado, Montana, Missouri, Kansas, and Utah, patients can walk into a lab and request certain tests; wellness centers offer health screens and other lab tests; and free-standing and mobile testing facilities offer screening tests to the public, such as in grocery stores and pharmacies.
Most DAT labs limit the availability of tests to simple, general health tests such as complete blood counts (CBC), cholesterol levels, throat and urine cultures, diabetes screening (blood glucose tests), chemistry panels, PSA for prostate cancer, thyroid tests, HIV antibody tests, blood typing, pregnancy tests, and urine drug screens.
Direct access testing may reduce costs for the patient by eliminating the expense of doctor’s office visits, providing vital information to patients who are concerned with a particular health problem or who may otherwise avoid testing due to inconvenience or concerns over anonymity. However, most insurance companies do not cover tests that are not ordered by a physician; therefore, you should expect to pay out-of-pocket for these services. In addition, labs providing DAT services must provide consumers with reference ranges and some assistance in interpreting the results. However, you are not operating under the guidance of your physician, who may be better able to determine what tests you really need but also what the results of those tests mean in light of your specific clinical signs, symptoms, and medical history.
