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 a urine sample at the same time every day. Avoid drinking large amounts of fluids 2 hours before collecting urine. 2. Immerse the test strip into the urine with one end up to the marked line. After about three seconds, remove the strip and place 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 sperm fertilizes the egg in the fallopian tube. Sperm can survive in the female reproductive tract for approximately 24 to 72 hours, while the egg is viable for about 24 to 36 hours after ovulation. Women should determine their menstrual cycle length before testing. A cycle is counted from the first day of menstruation to the day before the next period begins. Most women ovulate around 14 days before the start of the next period. The fertile window includes the 23 days before ovulation and the 12 days after, making pregnancy most likely during this time. Testing should begin at the appropriate time based on cycle length and continued daily as directed.
