C-reactive protein (CRP) is closely linked to rheumatoid arthritis and can be used to diagnose and monitor the disease. However, other factors must also be considered, and not all patients with rheumatoid arthritis will test positive for CRP. Doctors have known about the connection between CRP and rheumatoid arthritis since the 1980s. C-reactive protein (CRP) […]
PCR testing for HIV is accurate but requires trained professionals to read results. Antibody tests are commonly used and reliable after three months. PCR tests are expensive and not routinely used except for infants born to HIV-positive mothers. The polymerase chain reaction (PCR) test used to detect human immunodeficiency virus (HIV) is generally considered to […]
Polymerase chain reaction (PCR) amplifies DNA samples for analysis. PCR sensitivity amplifies even trace amounts of DNA, but contamination is a major concern. Sensitivity is critical in forensic analysis and can affect ancient DNA samples. The lab process and chemicals used can affect sensitivity, so documentation is crucial. Polymerase chain reaction (PCR) is a technique […]
Polymerase chain reaction (PCR) uses enzymes to replicate a portion of DNA for analysis. Taq polymerase, extracted from a bacterium, is key. PCR requires six components and involves denaturation, annealing, and extension. PCR has various uses, including paternity testing and DNA analysis of extinct species or crime scenes. Polymerase chain reaction (PCR) uses enzymes to […]
