Clinitek STATUS 
Purpose:
This procedure explains how to read the Bayer Multistix 10 SG urinalysis strips using
the Clinitek Status analyzer. This procedure has been prepared for use by the University
Hospitals (UUHSC) and Clinics.
Principle:
The analyzer is for use in the semi-quantitative detection of bilirubin, blood, glucose,
ketone, leukocytes, nitrite, pH, protein, specific gravity and urobilinogen in urine
samples.
The optical system consists of six light emitting diodes, a light guide, a mirror, a lens and
a detector. Light from the LED travels along the light guide and is reflected off the
calibration bar, or strip, onto the mirror. It is then directed through an aperture on the
lens, from where it is focused onto the detector. The light intensity detected is converted
into electrical impulses, which are processed by the instrument’s microprocessor and
converted into clinical results. When carrying out analysis on a urinalysis strip, the test
table positions strip pads in the “read area”. The light reflected at specific wavelengths
from the test pad is dependent upon the degree of color change in the pad and is directly
related to the concentration of the particular constituent in the urine. The analyzer’s
optical system images the entire strip (all at the same time).
Scope:
This procedure applies to medical personnel performing testing in the University
Hospitals (UUHSC) and Clinics. The Clinitek STATUS analyzer is considered waived
only when used with Bayer reagent strips, manufactured by Bayer HealthCare LLC.
Personal Protective Equipment (PPE):

Instrument Validation:
All validation material can be located in the Point of Care Department.
Backup Procedure:
If for any reason you are not able to utilize the Clinitek STATUS analyzer, you MUST
send the patient urine sample to the Clinical Laboratory for testing.
Note: send the sample in the appropriate transport tubes.
Method Limitations:

The sensitivities listed for each reagent are the generally detectable levels of the
analytes in contrived urines; however, because of the inherent variability of clinical
urines, lesser concentrations may be detected under certain conditions. The percentage
of clinical specimens correctly detected as positive increases with analyte
concentration.
If a positive nitrite is obtained on a patient sample from the Clinitek analyzer, visually
look at the completed urine dipstick that was interpreted by the Clinitek analyzer and
determine if the nitrite test pad is solid pink or only has pink edges. If the pad only
has pink spots or pink edges, the test pad should not be interpreted as a positive result.
With a black pen, cross out the positive result with one single line, write “negative”
adjacent to the original result and initial.
Each instrumental result represents a range of values. Because of specimen and
reading variability, specimens with analyte concentrations that fall between nominal
levels may give results at either level. Results will usually be within one level of the
true concentration. Exact agreement between visual results and instrumental results
might not be found because of the inherent difference between the perception of the
human eye and the optical systems of the instruments.
Definitive diagnostic or therapeutic decisions should not be based on any single result
or method.
Substances that cause abnormal urine color may affect the readability of test pads on
urinalysis reagent strips. These substances include visible levels of blood or bilirubin
and drugs containing dyes (e.g. Pyridium, Azo Gantrisin, Azo Gantanol),
nitrofurantoin (Macrodantin, Furadantin), or riboflavin.
Use fresh urine to obtain optimal results especially with the tests for bilirubin and
urobilinogen, as these compounds are very unstable when exposed to room
temperature and light.


Contamination of the urine specimen with skin cleansers containing chlorhexidine
may affect protein (and to a lesser extent specific gravity and bilirubin) test results.
Protein Test Pad:
 Urinary protein excretions can be temporarily elevated in the absence of renal
abnormality by strenuous exercise, orthostatic proteinuria, dehydration, urinary tract
infections, and acute illness with fever. Clinical judgment is needed to evaluate the
significance of “trace” results.
 Visibly bloody urine sample may cause elevated protein results.
Blood Test Pad:
 Certain oxidizing contaminants, such as hypochlorite, (bleach) may produce false
positive blood results.
 Microbial peroxidase associated with urinary tract infections may cause a false
positive blood reaction.
 The test is equally sensitive to myoglobin as to hemoglobin.
Leukocyte Test Pad:
 Elevated glucose concentrations (> 3g/dL) may cause a decreased leukocyte test
result.
 The presence of cephalexin (Keflex), Cephalotin (Keflin), or high concentrations of
oxalic acid may also cause a decreased leukocyte test result.
 Tetracycline may cause decreased reactivity, and high levels of the drug may cause a
false negative leukocyte reaction.
 Positive leukocyte test results may occasionally be due to contamination of the
specimen by vaginal discharge.
Nitrite Test Pad:
 Pink spots or pink edges on the nitrite test pad should not be interpreted as a positive
result.
 Nitrite concentration during infection increases with the length of time the urine
specimen is retained in the bladder prior to collection. A minimum of four hours of
bladder incubation significantly increases the likelihood of obtaining a positive result.
 A false negative nitrite result may occur with shortened bladder incubation of the
urine, absence of dietary nitrate, or the present of nonreductive pathological microbes.
Ketone Test Pad:
 False trace results may occur with highly pigmented urine specimens.


Clinical judgment is needed to determine the significance of “trace” results, which
may occur during physiological stress conditions such as fasting, pregnancy and
frequent strenuous exercise.
pH Test Pad:
 Bacterial growth in a urine specimen by certain organisms may cause a marked
alkaline shift in the pH (ph > 8.0) because of urea conversion to ammonia.
Specific Gravity Test Pad:
 Test strips read instrumentally are automatically adjusted for pH by the instrument.
 Highly buffered alkaline urines may cause low readings, while the presence of
moderate quantities of protein may cause elevated readings for the specific gravity.
Bilirubin Test Pad:
 Normal adult urine contains about 0.02 mg/dL of bilirubin, which is not detectable by
even the most sensitive methods. Even trace amounts of bilirubin are sufficiently
abnormal to require further investigation. When very small amounts of bilirubin in
urine are sought, confirmation testing is recommended.
 Atypical colors (colors that are unlike the negative or positive color blocks shown on
the color chart) may indicate that bilirubin-derived bile pigments are present in the
urine sample and may be masking the bilirubin reaction. These colors may indicate
bile pigment abnormalities and the urine specimen should have confirmation testing
performed.
