I had some blood drawn last Wednesday to be tested for celiac disease. How long should I wait to call them. Usually they call me if anything is wrong but I haven't heard anything. I suppose the results could be negative and I have nothing to worry about but either way I want to know.

Who is NIST and what do they do? NIST traceable calibration is an assurance program that certifies that a laboratory or manufacturer is fully equipped to calibrate equipment to National Institute of Standards and Technology (NIST) standards and that any products offered by that manufacturer will match those NIST-maintained measurement standards.
