For most air travelers, the risks to the fetus from exposure to cosmic radiation are negligible. For pregnant aircrew members ...

False-positive and false-negative test results can occur with any specimen, and caution should be exercised when clinical findings and laboratory results are discordant. Methods to rule out the presence of interfering substances include using a urine test, rerunning the assay with serial ...
