How to read test results


*** Ovulation Test

1. Positive

If two colored bands are visible and the test band is equal to or darker than the

control band, one will probably ovulate in the next 24-48 hours. If one wants to be

pregnant, the best time to have intercourse is after 24 but before 48 hours.


2. Negative

Only one color band appears in the control region or the test band is lighter than

the control band. There is no LH surge.


3. Invalid

A total absence of color in both regions indicates that the result is invalid. No visible band at all. Repeat test with a new test strip.


*** Pregnancy Test

1. Positive

Distinct red lines appear on the control and test regions. Both the test line and the control line indicate that you are pregnant. The color intensity of the test lines may vary. Different stages of the pregnancy have different concentrations of HCG levels.


2. Negative

Only one red line appears in the control region. No apparent line on the test

region. There is no pregnancy.


3. Invalid

No visible line at all. Repeat test with a new test strip.
