1. Collect urine in a clean and dry container. Do not use first morning urine. The best time to collect urine is between 10:00 AM and 8:00 PM. Try to use the urine sample at the same time each day. Avoid drinking large amounts of fluids 2 hours before collecting urine. 2. Immerse the test strip into the urine up to the MAX line, with the arrow end pointing toward the urine. After approximately three seconds, remove the strip and lay it flat. Read the result within 10 to 20 minutes. Do not read results after 30 minutes. The depth of insertion should not exceed the MAX mark line. Normal women ovulate each month. When an egg matures in the ovary, it is released and travels through the fallopian tube toward the uterus. Pregnancy occurs when a mature egg in the fallopian tube combines with sperm. Sperm can survive in the female reproductive tract for approximately 24 to 72 hours, while an egg remains fertilizable for about 24 to 36 hours after ovulation. Women should determine their menstrual cycle length before testing. A cycle is calculated from the first day of menstruation to the day before the next period begins. Most women ovulate approximately 14 days before the start of the next menstrual period. The most fertile window includes 23 days before ovulation and 12 days after, making 45 days around ovulation the optimal time for conception. Test regularly once beginning use.
