Testing PH and WBCs Before Sample Treatment or Dilution
TECHNICAL BULLETIN: USING QWIKCHECK TEST STRIPS
Thursday, October 31, 2013
QwikCheck™ Test Strips are for in vitro diagnostic use for the determination of pH and
leukocytes (WBCs) in semen. Test results are determined by comparing the color of the
test patches to the color chart provided on the bottle label.
Normal values for semen pH are generally ≥ 7.2; the pH pad reports a range of 5.0 to
8.5. Normal values for semen Leukocytes are < 1 M/ml; the Leulocyte pad reports semiquantitative results: NEG is <1M/mL and POSITIVE is ≥1 M/mL.
Follow the instructions provided in the package insert for testing and for determining the
results. Because test results can be impacted by drugs or other chemical use, run the pH
and WBC tests on untreated semen and PRIOR to any sample treatment (Chymotrypsin,
enrichment) or dilution (washing, dilution, etc.).
Test the sample PRIOR to any sample treatments or dilutions (chymotrypsin,
enrichment, washing, etc.) as test results may be impacted due to erroneous color
