PCR Test
A polymerase chain reaction test, a laboratory method that amplifies and detects specific genetic material to diagnose infections and conditions. Widely used for pathogens like SARS-CoV-2, PCR tests are highly sensitive and often serve as preoperative screening to confirm patients are safe to proceed.
What is a PCR Test?
A PCR Test uses polymerase chain reaction (PCR), a laboratory technique that copies and amplifies specific segments of genetic material so they can be detected even when present in very small amounts. This amplification is what gives the method its high sensitivity.
PCR tests are widely used to detect pathogens, including the virus that causes COVID-19, as well as other infectious and genetic targets. Because they identify genetic material directly, they can confirm the presence of an organism with strong accuracy.
How is a PCR Test used around surgery?
In surgical settings, PCR testing is sometimes used as preoperative screening to confirm a patient is not carrying an active infection that would make proceeding unsafe or require special precautions. A clear result supports the decision to move forward with a scheduled procedure.
For ambulatory surgery centers, predictable preoperative screening helps keep the day's schedule intact, since an unexpected positive result can require rescheduling. Reliable testing therefore supports both patient safety and smooth operational flow.
