WebJan 26, 2024 · PCR testleri virüsü tespit edebilir hale gelene kadar, kişiden alınan genetik materyali üç adımdan oluşan bir döngüde çoğaltarak çalışıyor. Bir örnekteki virüsü tespit etmek için gereken döngü sayısı ise “döngü eşiği” (cycle threshold) olarak biliniyor. WebJul 27, 2024 · They found that the amount of cycles needed to detect the virus in the patients ranged between 14 and 45. Cycle thresholds are important for several reasons. Some types of PCR testing, called qualitative PCR tests, indicate whether a sample is positive or negative based on a limited number of cycles.
