In most cases, a negative physical examination is better, for example, when checking for HPV or HIV, a negative result means that there is no infection with either virus. Also, a routine urine test is normal if the urine is negative for red blood cells, white blood cells, and urine protein. If the urine is positive for red blood cells, it often represents damage to the glomerulus, possibly due to glomerulonephritis or contamination from menstrual blood. If the urine is positive for protein, it represents a problem with the kidneys, possibly nephrotic syndrome. So in most cases, a negative physical test is a very good result, while a positive physical test is bad. But there are exceptions, for example, when doing the five tests for hepatitis B, if the surface antibody for hepatitis B is positive, it means that the body is immune to the hepatitis B virus, which is the result that everyone wants and the result that they want to get after the hepatitis B vaccine.
