Ct ratio explained
WebJan 11, 2024 · Note that when a Ct ranges above 38 or between 38 to 40 or more, it indicates contamination, infection or less nucleic acid present in a sample. Factors … WebFirst we need to remember that the ratio of 200:5 can also be written as 200/5 or 200 divided by 5. This is the first calculation that we need to do as this will give us the multiplier. So 200/5 = 40. Thus, our multiplier is 40. Now we can divide 100 by …
