In Reply Dr Rothschild points out that urine dipstick testing is not accurate for detection of microscopic hematuria. We fully agree with this point, and we noted in our Invited Commentary1 that asymptomatic microscopic hematuria (AMH) should be defined as 3 or more red blood cells per high-powered microscopic field on urine microscopy and should not be based on dipstick results.
