How PCR Test Services Help You Stay Safe And Sound From Covid-19

PCR Test Services

Access to rapid diagnosis is essential for the control and management of severe acute respiratory syndrome coronavirus 2, also known as Covid-19. Laboratory-based PCR testing is the current standard of testing and care, but typically requires a centralized laboratory and significant infrastructure for PCR test in Hyattsville MD

PCR is described as the evaluation of the diagnostic accuracy of a new virus. As demand for PCR diagnostic testing services continues to outstrip capacity, clinicians are thinking carefully about when to recommend PCR diagnostic testing for Covid-19. PCR testing is now free and painless, helping individuals and families stay healthy. 

Since the start of the pandemic, labs and pharmacies have partnered with communities to make reliable and rapid COVID-19 testing more accessible to everyone. Several labs and pharmacies make sure to provide your Covid-19 test results within 24 hours of your test administration or you will receive a full refund of the purchase price you paid for the test. In this article, you are going to find all about PCR and PCR test services.

First Of All, What Is A PCR Test?

PCR or also known as “polymerase chain reaction test” is a fast and highly accurate way of diagnosing certain infectious diseases and genetic changes. The tests work by finding the DNA or RNA of disease-causing irregular cells in a sample.

The PCR test in Hyattsville MD examines your upper respiratory tract sample for genetic material ribonucleic acid, or RNA from SARS-CoV-2, the virus that causes COVID-19.

Scientists use PCR technology to drive small amounts of RNA from samples into deoxyribonucleic acid (DNA), which replicates until SARS-CoV-2 is detectable if present. Dissimilar to many other tests, PCR tests can find an indication of disease in the early stages of infection.

Some other tests may miscue early signs of disease because there are not enough viruses, bacteria, or other pathogens in the sample or your body hasn’t had enough time to mount an antibody response.

PCR tests can distinguish diseases when there is only a very small number of pathogens in your body. The PCR test has been the standard test for testing and diagnosing COVID-19 since its authorized use in 2020. It is the most accurate and reliable to date.

Why is the PCR test necessary?

There are a few things that indicate the need for a PCR test in Hyattsville MD:

  • The person has symptoms of COVID-19, such as fever, cough, fatigue, or shortness of breath.
  • One of them was in close contact with someone with COVID-19. Close contact means he has been within 2 meters (6 feet) of someone who has COVID-19 or lives with someone who has COVID-19. If you have been in close contact with someone infected with the COVID-19 virus, get tested at least five days after you came in contact with that person.
  • A health care provider, another health professional, or your public health department recommends getting tested and you are not fully immunized.
  • You must take a test for evaluation pursuits, such as in some schools or workplaces.

Types of PCR tests

PCR testing services adopt different ways to obtain a sample for a PCR test. Methods include blood tests and nasal swabs tests for COVID-19.

  1. Blood test

During a blood test, a health professional will take a sample of blood from a vein in your arm with a small needle. A needle is inserted and a small amount of blood will be collected in a test tube or vial. It only takes a few minutes.

  1. nasal swab test

A nasal swab can be taken from the upper part of the nostrils known as “anterior nostrils”. It can also be taken from the back of the nostrils, in a procedure known as a nasal mid-turbine “NMT” swab, or from the nasopharynx, the highest part of the nose and throat.

Steps For The COVID-19 PCR Test

There are three main steps:

  • sample collection

PCR testing services or a certified health care provider uses a swab to collect the respiratory material found in your nose. A swab is a soft tip on a long, flexible stick that is inserted into the nose.

  • Extraction

When a scientist or lab technician receives the sample, he or she isolates (extracts) the genetic material from the rest of the sample material.

  • The PCR

Then the PCR step uses special chemicals and enzymes and a PCR machine called a thermocycler. Each cycle of heating and cooling increases the amount of target genetic material in the test tube. After many cycles, masses of replicas of a small part of the genetic material of the SARS-CoV-2 virus are present in the test tube.

Who should be tested for COVID-19?

A health care provider or a doctor may recommend testing for certified or labs for COVID-19 if you have any of the following signs:

  • Cough.
  • Fever and/or chills.
  • Shortness of breath or difficulty breathing.
  • Tiredness.
  • Muscle or body pain.
  • Headache.
  • Nausea or vomiting.
  • Diarrhea.
  • Loss of taste or smell.
  • Throat pain.
  • Congestion or runny nose.

Some people have COVID-19 but have no symptoms or are said to be asymptomatic. These patients can still spread the COVID-19 virus to others. People without symptoms can get tested as well. If people without symptoms test positive, they should also follow self-isolation procedures to help slow the spread of the virus.
