TB PCR In Delhi

The TB pcr test in Hyderabad is done to check the presence of both latent and active tuberculosis bacteria. In fact, PCR is considered to be a highly sensitive and effective testing method. Tuberculosis development happens in three stages:

• Primary infection is when the person is first exposed to the bacteria. This can be due to visiting places where tb infection rates are high or working with patients infected with tuberculosis.
• Latent infection is the presence of the strain even after the primary immune system of the body. The bacteria remain in a dormant stage and the person is not contagious. Often people infected with tuberculosis carry the bacteria and it does not reactivate.
• Active infection is when the immune system failed to suppress the infection and the person becomes contagious, showing signs of tuberculosis infection. Often the infection spreads to the spinal cord or brain from the lungs.

The tb pcr test is done via collecting blood samples. When done by experienced technicians, the process of inserting the needle and drawing blood can be fast and almost painless. Some people might feel dizzy or see bruising around where the puncture was made. But, these are temporary side effects and leads to no fatality. Sometimes, sputum can also be collected and PCR to be done on the sample to detect the presence of the bacteria.

Sometimes the patient who has active tb might not show symptoms. But, a chest X-ray will yield positive results.

Being a bacterial infection, tuberculosis can be dealt with by the body’s immune system. The stronger the immune system, the more protection the person gets against infections.
