If you need it, ask that a more sensitive test be done -- a blood test
for cocaine metabolites. This may cost
you, but it will prove that this test
result was an anomaly.
But don't be surprised by a suspicious doctor. A couple of years ago a conscientious pain doctor I know, a man whom I respect as a doctor and as a pain patient advocate, once reported his astonishment over finding UDT results that were positive for cocaine in his patients who are now in their 70s.
