One Step LH Urine Ovulation Test is fast and easy-to-use. It is a qualitative test that can predict when there is a LU(luteininzing hormone) surge and in turn when you are likely to ovulate.

When To Begin Testing

First, you must determine the length of your menstrual cycle. This is the number of days from the first day of your menstrual bleeding to the day before your next bleeding begins again. Please refer to the chart to determine when you should start testing. If your cycle is shorter than 21 days of longer than 38 days. Consult your doctor. If you do not know your cycle length, you may begin the test 11 days after your first period since the average cycle length is 28 days. Perform 1 test each day over a 5 days period or until the LH surge has been detected.

URINE COLLECTION

• Do not use first morning urine samples as LH is synthesized in your body early in the morning urine samples as LH is synthesized in your body early in the morning. It will not show up in your urine until later in the day.
• the best time to collect your urine is between 10 am-8pm
• Collect urine at about the same time each day.
• Reduce liquid intake about 2 hours before collecting your urine as a diluted urine sample can prevent the test from detecting LH surge.

TEST PROCEDURE

• Allow the sealed LH test pouch, patient’s urine sample and control solution to reach room temperature(18-30℃)
• Remove the LH test device from the sealed pouch
• Immerse the strip into the urine with the arrow end pointing towards the urine. Do not immerse past the MAX(MAXIMUM) line. Take the strip out after 5 seconds and lay the strip flat on a clean, dry, non-absorbent surface(e.g. mouth of the urine container) in the test specimen, positive results may be observed in as short as 40 seconds. However, to confirm negative results, the complete reaction time(10 minutes) is required. Do not read results after 30 minutes.

INTERPRETATION OF RESULTS
No LH surge: Only one color band appears on the control
region or the test band is lighter than the control band
there is ot LH surge.
LH Surge: if two color bands are visible and the test band
is equal to or darker than the control band, one will
probably voulate 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.Invalid: No visible band at all. Repeat
test with a new test kit.

STORAGE AND STABILITY
The test kit can be stored at room temperature(18 to 30℃) in the sealed pouch to the date ofexpiration. The tes kit should be kept away from direct sunlight, moisture and heat.
