Bookmark In this experiment a standard curve was not run. Only two standards were used, one for total cholesterol and one for HDL cholesterol. Give at least one specific example of a situation in the lab where an error would not be detected by running only one standard but would be detected if you ran a standard curve. How does this reflect on the validity of many clinical tests today where the technicians do not run standard curves? This question is from a Cholesterol (Total and HDL) Content of Blood Serum, Biochem LAB

Solution

Since a standard curve, is a calibration curve, in which samples with known properties are measured to generate a graph that is used to determine unknown samples by interpolation on the graph in this type of a quantitative research technique. So the validity of clinical tests that are done is questionable without a standard curve for quantitative research done spectrophotometrically.
