Test Code UACS UA Chemical Dip with Reflex Sediment, Culture if Indicated

Important Note

First morning clean catch urine specimen is preferred. 

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

Reflex sediment examination will only be performed if the chemical dip is positive for Protein OR Leukocyte Esterase OR Hemoglobin.

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.
