Certain viral infections and genetic alterations can be quickly and accurately diagnosed using PCR (polymerase chain reaction) tests. In order for the tests to function, a sample must include the DNA or RNA of a pathogen (an organism that causes disease) or aberrant cells. There are reputed multispecialty centers that offer effective PCR tests In Abu Dhabi.

Let’s unravel a few important things about PCR test

All living things have genetic material called DNA that includes instructions and data. Another form of genetic material is RNA. It is important in the production of proteins and holds data that has been copied from DNA.

PCR tests are used to:

Identify specific infectious illnesses
Find a genetic alteration that can lead to disease
Detect cancer cells in minuscule quantities that may go undetected by other tests.

How do they function?

PCR tests function by:

Obtaining a sample of tissue, blood, mucous, or saliva
The sample will include your DNA as well as possible pathogen or cancer cell DNA.
The sample is placed in a unique device. The material is amended with an enzyme called polymerase. The sample makes copies as a result.

The copying procedure is carried out repeatedly. There are billions of copies created after about an hour. It will be noted on the machine if a virus or pathogen is present.
Instead of DNA, some viruses, including COVID-19, are composed of RNA. These viruses require RNA to be converted into DNA before replication. It is known as reverse transcription PCR (rtPCR).

Is there any risk associated with PCR tests?

The danger of getting a blood test is extremely low. Even though you can have some minor discomfort or bruising where the needle was inserted, most side effects are transient.

Your throat may feel tickly or you might cough after using a nasal swab. Uncomfortable nasopharyngeal swabs can make you gag or cough. All of these effects are passing.

You must look for highly recognized and licensed medical polyclinic centers that conduct PCR tests in Abu Dhabi by top-rated medical experts.
