Important Note

First morning clean catch urine specimen is preferred. 

Indicate source when submitting (i.e. clean catch, cath).

Culture will be reflex ordered only if:

The dip is positive for Nitrite OR Leukocyte Esterase

OR

The sediment examination reveals  >= 10 white cells / hpf AND >= 2+ bacteria.
