| Effective September 4, 2001, Clinical Pathology will be using the
Criterion II Urine Analyzer to read CHEMSTRIP dipsticks. Until now,
semi-quantative chemistry tests on urine have been performed by visual
assesment of MULTISTIX® dipsticks. The Criterion Urine Analyzer
/ CHEMSTRIP® system incorporates a color compensation pad to aid
in correcting interference from the color of the urine itself. Results
will be reported with units of concentration, e.g. mg/dL, except for
pH and hemoprotein. The reported concentration is the minimum amount
of analyte that will cause a color change of a given intensity of
the pad and not the exact concentration. For example, a protein pad
that has a color read as 50 mg/dL may have a protein concentration
anywhere in between 50 to 100 mg/dL (the next minimum amount of analyte
producing a color change). Since the dipstick pad "blood"
or "erythrocytes" undergoes a color change in the presence
of both the hemoprotiens hemoglobin and myoglobin, this test will
be now titled "hemoprot," to better reflect the true nature
of a positive result.
Below is an image of our routine urinalysis report. The test titles
appear as the parameter preceded by a "c" to designate
that the Criterion Urine Analyzer was used. If the instrument is
not working and the CHEMSTRIP® is read manually, the parameter
name will not be preceded by a small "c".

of the individual tests.
