Laboratory problem: The efficiency of specific testing can be affected by a variety of problems. It may be dependent on the laboratory testing material, the efficiency of the testing, machine error, human error etc. The testing results needs to be filtered by your physician. Your doctor can also contact the lab to have them explain this disagreement.
