INTERPRETATION OF RESULT
Two distinct color bands appear - one on the control and one on the test region.
This indicates that pregnancy has been detected. The color intensity of the test bands may
Only one color band appears on the control line, and no band appears on the test
region. This means there is no pregnancy detected.
There are no visible bands at all, or if one red band appears only on the test region.
If this happens, repeat a new test. If test still fails, please contact the distributor with the
5. Repeatability and Reproducibility -
Three lots of Kardioline HCG Urine Pregnancy
Test were used and 10 strips of each lot were tested in HCG standard solution with different
concentrations prepared at 0 mIU/ml, 25 mIU/ml and 100 mIU/ml.
Testing of quality control material to verify the performance of the test is recommended for each new lot of test. In addition, users should follow their state and local regulations and
guidelines regarding GLP requirements. In addition, a built in procedural control is being
used designated as control region (C) on the test device to indicate that sufficient sample

1. Sensitivity -
Kardioline HCG Urine Pregnancy Test will display positive results with
specimens containing HCG at the level close to or greater than 25mlU/ml.
LIMITATION OF THE PROCEDURE
2. Specificity -
The following compounds exhibited no interference when dissolved
in urine, which had HCG levels of 0 and 25mlU/ml.
1. Alcohol may interfere with test result. It is not recommended using the test after drinking.
2. Occasionally specimens containing less than 25mlU/ml for urine also yield positive results.
