SpletThis cycle repeats 25 25 - 35 35 times in a typical PCR reaction, which generally takes 2 2 - 4 4 hours, depending on the length of the DNA region being copied. If the reaction is efficient (works well), the target region can go from just one or a few copies to billions. Splet27. apr. 2024 · In practical terms, the limit of detection (LOD) for an RT-PCR test tells you the minimum amount of RNA that the test will detect 95 out of 100 times. If the limit of detection (LOD) for a test is too high, patients who are infected with SARS-CoV-2 may not test positive, leading to a high rate of false-negative results. sheran hotel https://euromondosrl.com
