PCR Tests

PCR was invented in1983 by a Chemist named Kary Mullis, who was later awarded a Nobel Prize in 1993 for this landmark invention.

PCR stands for Polymerase Chain Reaction. PCR Diagnostics,  also known as Molecular Diagnostics or Nucleic Acid Amplification Tests (NAATs means that in the sample being tested, we aim to detect nucleic acid molecules (DNA or RNA) to arrive at a diagnosis or provide clinically useful information for patient care.

DNA stands for Deoxyribonucleic acid while RNA stands for Ribonucleic acid. These nucleic acid molecules are the tapes of life and they are found in all living cells e.g. of humans, bacteria such as TB germs, viruses such as HIV or Coronaviruses (SARS-CoV-2), parasites such as hook worms, fungi such as Candida, e.t.c.

Thus, when we detect DNA or RNA of any of these germs, we are able to tell that the sample contains those germs which must therefore be targeted during patient treatment. In the case of humans, when the DNA is changed in any way such as in sickle cell disease, detection of those changes in the DNA means that a certain disease such as sickle cell is present in the patient.

Therefore, through PCR diagnostics, we detect many diseases. At MBN Clinical Laboratories, examples of diseases OR germs detected using PCR/molecular diagnostics include:
