Designing reproducible PCR assays involves optimizing multiple moving targets, from standardizing each component in sometimes minute reaction volumes to planning ahead to ensure long-term and secure ...

Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

Researchers often call the polymerase chain reaction test – known as the PCR test – "the gold standard" for detecting the COVID-19 virus. The test is considered highly reliable and effective, and it ...

A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.

A new biotechnology company in McKinney has ambitions to become the world’s first fully integrated platform for polymerase chain reaction (PCR) testing — the same technology behind a common COVID-19 ...
