![]() As each new strand of DNA then becomes a template for subsequent rounds of replication, the amount of target sequence is dramatically amplified. The chain reaction occurs as the template is heated to strip apart the double helix, cooled to allow the polymerase to synthesize a new strand of DNA using one of the parent strands as a template, and then allowed to zip back up before the process starts again. ![]() The polymerase chain reaction-usually known simply as PCR-is so named in part for the polymerase enzyme that uses primers bound to a DNA template to assemble a new strand of nucleic acids. As the technology advances and costs drop, however, clinical labs are increasingly incorporating PCR techniques into their repertoire of diagnostic tests. Even then, specimens are often run in periodic batches, which can add several days of waiting time to a 1-hour PCR test. Until recently, the use of PCR has been restricted to a small number of laboratories that have the dedicated space and technical skill to perform complicated molecular diagnostics procedures. “PCR is a fast, accurate, and highly sensitive method that can be used for a broad range of genetic tests that identify infectious organisms or influence cancer therapy,” said David Persing, MD, PhD, executive VP and chief medical and technology officer at Cepheid, Sunnyvale, Calif. In terms of infectious disease diagnostics, even miniscule amounts of pathogen-specific DNA or RNA can be artificially amplified, detected, and measured in just a few hours without the need to culture the specimen-a task that can be very difficult for some infectious agents. Before PCR, this level of specificity, sensitivity, and speed did not exist. This type of test is sensitive enough to pick up small variations in genetic sequence and can be quantified to determine the relative amount of DNA in a sample. Please call 803.756.3460 and our Pharmacist will review a series of questions to ensure you are eligible for this medication.RReal-time PCR (polymerase chain reaction) provides clinical diagnostic labs with the ability to specifically target a particular sequence of human or pathogen DNA or RNA and amplify it to a level that can be detected and measured. Yes, our Pharmacist at the Lexington location can prescribe oral medications that reduce the severity, duration, and complications from COVID-19. If I tested positive for COVID-19, can I be prescribed a medication. For more information on this, please call the pharmacy. As a reminder, PCR results can take 2 days before results will be visible. You can retrieve your results anytime by visiting. Some cellular carriers will block text messages from coming through to your phone. I did not receive my results of my test via text. ![]() Yes, we do have a same day RT-PCR option listed above that takes approximately 1 hour to receive your results. Do you have a same day RT-PCR that will suffice for travel? ![]() Yes, our PCR test detects RSV, influenza A, B, and Covid-19. We also conduct a PCR test which detects the same as well as RSV. Yes, we typically conduct a rapid antigen test that detects influenza A, B, and Covid-19 if you’re experiencing symptoms. Unfortunately, My Pharmacy cannot guarantee timing on PCR results. However, due to demand fluctuations results can take up to 2 days depending upon volume of testing at any given time. We strive to complete PCR testing as quickly as possible. Sundays are staffed only if appointments are made by the prior Thursday at 5:00 pm. Please refer to our testing page on our website that details the hours of operation at our Lexington location.Īppointments are not required except for Sundays. – We recommend obtaining a PCR test to confirm any negative Rapid antigen test. For additional questions, please ask an associate prior to starting your test(s). It is a quick and reliable test however the PCR test is the “gold standard” test and is sent out to our lab and analyzed and used as a confirmatory test. What is the difference between a Rapid antigen test and a PCR test:Ī rapid antigen test detects the presence of circulating virus in the nasopharynx area. Your results will be texted to the phone number you provide at the time of testing. You will receive your results within 10-15 minutes after completing the test. How long does it take to receive my results from a Rapid COVID and/or COVID & FLU Antigen test? ![]()
