Please refer to the Instructions for a diagram to supplement the following result descriptions:
POSITIVE: Distinct pink-colored line appears in the control and test regions, and the test line (T) is equal to or darker than the control line (C), indicating one will probably ovulate in the next 24-48 hours. If trying to get pregnant, the best time to have intercourse is within 24 hours of obtaining a positive test.
NEGATIVE: Only one pink line appears in the control region (C) or the test line (T) is lighter than the control line (C) indicating a very low level of LH in urine, which is a negative result for ovulation.
INVALID: No visible band appears in the control region (C). Repeat with a new test strip. If the next test is also invalid, please take note of the lot number on the packaging and contact us at firstname.lastname@example.org
