The electronic test for jaundice has some error and may give a slightly higher result than the serum test for jaundice, which is most accurate through serum testing. Jaundice is a yellowing of the skin and mucous membranes due to increased bilirubin in the serum. Clinical tests for jaundice include electrodiagnostic tests and serologic tests. Electronic test for jaundice is to measure the bilirubin index in the body through the skin. The advantage of electronic test for jaundice is that it does not have any trauma, etc., and it is one of the more frequently used ways for clinical test for jaundice at present. Serum test for jaundice is done by drawing blood from the vein, and then the concentration of bilirubin inside the serum is detected, and the result of serum test for jaundice is the gold standard, which is the most accurate. Although there is an error in electronic jaundice detection, the error is generally small, if the measured values are within the normal range, there is no need for special treatment, if the jaundice index is on the high side, you need to carry out serum testing in time. If bilirubin is found to be elevated, the cause of the disease should be clarified, such as liver factors, biliary factors, destruction of red blood cells in the blood, etc., and appropriate measures should be taken to deal with the cause of the disease.
