Polymerase chain reaction (PCR) is a molecular biology technique used to multiply certain deoxyribonucleic acid (DNA) fragments. Application The exponential amplification via reverse transcription polymerase chain reaction provides for a highly sensitive technique in which a very low copy number of RNA molecules can be detected. Abstract. Missed cases when sputum analysis is only used and over treatment in cases where immunological tests identify immunized pts or patients with quiescent primary infections as cases off disease. The polymerase chain reaction (PCR) has revolutionized the detection of DNA and RNA. Clinical applications using digital PCR. 76-89. SUMMARY Real-time PCR has revolutionized the way clinical microbiology laboratories diagnose many human microbial infections. However, antibody detection is still limited by its tendency to return negative results during the early phase of aforementioned diseases. Very sensitive (3pg or 1 genome eq of DNA). The polymerase chain reaction (PCR) is used to make millions of copies of a target piece of DNA. In recent medical field, Western Blot has a wide range of applications in medical diagnosis, such as the application of medical diagnosis for HIV (Human Immunodeficiency Virus) infection, BSE (Bovine Spongiform Encephalopathy, also known as "mad cow disease"), FIV (Feline Immunodeficiency Virus), HBV (Hepatitis B Virus) infection, and so on. Real-time polymerase chain reaction is highly sensitive for detection of minimal residual disease in hemic malignancies. The use of PCR in diagnosing genetic disease, whether inherited genetic changes or as a result of a spontaneous genetic mutations, is becoming more common.  This technique, in spite of its success, is not without its limitations.
