Advanced Medical Diagnostics of Texas uses Polymerase Chain Reaction (PCR) technology to detect a vast number of individual infections. PCR testing is also used to detect genetic indicators present in a person’s genetic profile to help make health predictions and guide decisions for a healthier, happier life. Physicians and patients are able to access their results via an online portal. Currently, COVID-19 results are available within 24 hours of specimen arrival at the lab (with same-day results available in Texas). Please contact the lab for specific details and to schedule a test.
