The procedure is carried out on the first day of the delay in menstruation. Despite the fact that most manufacturers recommend manipulation in the morning, nevertheless, you can get a reliable indicator at any time. For this you need:
• prepare a clean container for urine - for tablet or standard designs;
• wash - for jet devices.
After the manipulations are performed, and the required amount of urine falls on the indicator, the result is evaluated after 5 minutes. Too early assessment of the result or delay is the cause of erroneous interpretation.
