Instructions
Positive screening results are unconfirmed and are to be used only for medical (i.e. treatment) purposes. Unconfirmed screening results must not be used for non-medical purposes (e.g. employment testing).
Only positive maternal and neonatal screening results reflex for confirmation and are reported separately

Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
Adulterants, such as bleach or other strong oxidizing agents, added to urine specimens may produce erroneous results regardless of the method of analysis. If adulteration is suspected, obtain another specimen.
Methodology
Enzyme Immunoassay
Setup Schedule
Daily
Reference Range
Creatinine < 20.0, normal specific gravity
Urine creatinine level is between 0 and 20 mg/dL indicating possible sample dilution or patient fluid loading which may impact accuracy of the results provided. Specific gravity is normal.
Creatinine < 20.0, abnormal specific gravity
Urine creatinine level is between 0 and 20 mg/dL and specific gravity is abnormal indicating that sample is diluted, non-physiological, invalid, abnormal or substituted
