Polymerase Chain Reaction is a very accurate technique employed in laboratories throughout the world. The PCR mixture combines primers with DNA to create copies for testing. DNA tests provide evidence to show that a suspect was involved in a crime or to determine paternity. While this technique has been used in labs for quite some time, it is now available to use on home test kit samples. The private home test kit option is appropriate for those who desire to learn more about familial relationships as well as find genetic markers for disease. You can get a test kit at your local drugstore or online for your individual needs and mail you samples to the lab.
Your test samples will be analyzed for the specific reason you selected. The results may be available within a matter of days online or take a little longer to reach you by mail. A complete genetic report is included with each test. You may require the help of a physician or lab technician to understand all the nuances and how to proceed.
When tests are performed at your ‘doctor’s office, it is essential that the outcomes are incorporated into your health record. If it comes out positive for certain illnesses, a second test is done known as the Western blot test. If you’re performing your tests at home, it’s ideal to find expert guidance to evaluate results as they are not error-proof. Positive tests should be followed by another.
For example, an HIV test directly measures the quantity of a virus or bacteria in an individual’s blood. But the test may not be able to pick up HIV infections pcr test for up to 3 months after an individual is infected. If you get a positive hepatitis C antibody test, it does not absolutely mean that you are infected either. There’s a possibility that you might have been infected with hepatitis C previously, but you’re no longer infected. All in-home tests are made to detect HIV-1, hepatitis C, and hepatitis B. Donors with a positive result for these disease markers should be reentered and verified.
The main advantages of using PCR are speed and convenience. The Taq polymerase is particularly helpful for laboratory testing because the enzyme used doesn’t break down at the temperatures necessary to do the test. Susceptibility of disease can be tested, but it isn’t routinely performed by a doctor. But you can buy your own test kit to keep an eye out for genetic predispositions and take the results to them. By detecting genetic markers early, your doctor may benefit from real-time strategies toward a particular treatment.
Genetic home testing labs can be found online with websites that describe their services and fees. They should offer DNA advisors to answer any questions that could have about testing at home or to allow you to schedule an appointment for examination at their facility. Be sure both you and your healthcare practitioner are cautious when comparing test results from various sources.
