The Ovulation Predictor Kit is designed to detect the increase of LH and

thus predict the time you are most able to conceive.

Do not use after Expiration Date.

Store in a dry place at room temperature.

For In Vitro use only.

Keep out of reach of children.

Do not open foil pouch until ready to start the test

HOW THE TEST WORKS

The Ovulation Predictor Kit is a test for detecting an increase of

luteinizing hormone (LH) in your urine. Normally, about 1 or 2 days before

the middle of each menstrual cycle, the level of this hormone will increase

suddenly (this is called the LH surge). Usually, an egg is released from

the ovary 24 to 36 hours after the LH surge (this process is known as

ovulation). The released egg can only be fertilized during the next 24

hours. In order to maximize the chance of becoming pregnant, it is

recommended that intercourse take place within 2 days

after you detect your LH surge.

WHEN TO START TESTING

To find out when to begin testing, determine the length of your normal

cycle. This is the number of days from the first day of menstrual bleeding

(which is considered Cycle Day 1 " CD 1 " ) to the day before the bleeding

begins again. Take the first day of bleeding as Day 1 and mark it on the

calendar. Use the following chart to determine when you should start

testing.

Cycle Length ~ Begin Testing On CD

21 ~ 6

22 ~ 7

23 ~ 8

24 ~ 9

25 ~ 10

26 ~ 11

27 ~ 12

28 ~ 13

29 ~ 14

30 ~ 15

31 ~ 16

32 ~ 17

33 ~ 18

34 ~ 19

35 ~ 20

36 ~ 21

37 ~ 22

38 ~ 23

39 ~ 24

40 ~ 25

Note: If your menstrual cycle is typically longer than 35 days or shorter

than 21 days,

you should consult your physician for the recommended day to start testing.

You may test at any time of the day at your convenience, however, late

afternoon seems to be the most popular time. You should test at

approximately the same time each day.

Do not consume an excess amount of liquid for at least 4 hours prior to

performing the test,

to avoid the dilution of LH in your urine.

HOW TO PERFORM THE TEST

1. Test in the late afternoon after not drinking excess liquids and holding

your urine as long as possible before testing to insure potency of specimen.

2. Collect urine using a clean, dry container. If the test will be carried

out after more than 1 hour

from the time of urine collection, the urine should be refrigerated. If

refrigerated, urine should be allowed to warm to room temperature before

testing.

3. When your are ready to begin the test, open one of the foil pouches

(open one at a time, immediately before testing). Remove the test device

from the foil.

4. Draw urine up to the marked on the pipette provided (approximately 5

drops). Dispense entire content of the pipette into the sample well. Wait

3 minutes for the result to develop.

5. Read results between 3 -5 minutes.

INTERPRETATION OF RESULTS

1. If there is no line in the test region (T), or the line is lighter than

the one in the control region ©,

then you have not begun your LH surge and you should continue to test daily.

2. If the color of the line in the test region is equivalent to or more

intense than the line in the control region, you have detected your LH

surge. Ovulation should occur within 24 to 36 hours.

NOTE: All tests are independent of each other. It is not recommended to

compare readings as the results can change in time.

QUESTIONS AND ANSWERS

Q: Is timing critical in getting an accurate result?

A: Yes, a timer is suggested to monitor the observation time. The color

intensity of both the test and the control bands increases over time. The

rate of increase may different between the two bands. Thus the test should

be read within the specified time (3-5 minutes).

Q: Do I continue testing after the LH surge is detected?

A: No, you can stop testing when you detect your LH surge and save the

remaining tests for next month, if necessary.

Q: What if neither the test band nor the reference band appears in the

window?

A: Make sure enough urine (5 drops) is applied to the sample well. If you

do not see that the urine has migrated up the membrane through the window,

the test is void.

Q: What could interfere with my test result?

A: If you are pregnant, have recently been pregnant or have reached

menopause,

you may get a misleading result. This may also be true if you are taking

drugs or receiving injections, which contain hCG or LH.

Q: What if the LH surge is not detected?

A: If the LH surge is not detected after 5 days of testing, you may have

miscalculated your test start day. Continue testing with the same brand of

Ovulation Predictor Kit (do not switch brands).

If your LH surge is not detected, consult your physician.
