Because a Pediatrician’s primary focus is dealing with diseases, pediatricians in general are not aware of the revolving door of designer drugs, nor do they understand the techniques and instrumentation a Toxicology laboratory uses. Pediatricians are not familiar with the different laboratory panels or testing combinations labs offer, or don’t offer at all. This is very important because the pediatrician is the one who selects the type of testing to be done.
Because the American Board of Pediatrics doesn’t want to damage the rapport between the doctor and the patient, most pediatricians won’t test your child for drugs if the child says s/he doesn’t want to be tested.
