Detection of human chorionic gonadotropin (hCG) in urine (pregnancy test)


▼Usage and dosage
【Timing for testing】
You can start testing approximately one week after the expected date of menstruation.
【Urine used for testing】
Urine at any time of day can be used for testing.
【How to test】
Urine can be tested in the morning, noon, or night.
1. Attach the cap to the back
Open the aluminum bag immediately before testing, take out the check stick, and attach the cap to the rear of the check stick.
2. Dip the entire urine-absorbing part for 2 seconds
Hold the urine-absorbing part facing downward, and dip it in urine for 2 seconds, or collect urine in a clean, dry paper cup and immerse the entire urine-absorbing part for 2 seconds so it is fully submerged. (Perform the test as soon as possible after collecting urine.)
Be careful not to wet anything other than the urine-absorbing part with urine at this time.
If testing with collected urine, only immerse the urine-absorbing part.
Do not dip for longer than 10 seconds or less than 10 seconds.
3. Place horizontally and wait for 1 minute
Do not hold in your hand while waiting!
With the urine-absorbing part facing downward, attach the cap, place on a flat surface with the judgment window visible, and wait for 1 minute.

【How to interpret results】
● First, confirm that a red line appears in the end display part of the check stick. The judgment is made by observing the presence or absence of a red line in the judgment display part.
● Avoid interpreting results after more than 10 minutes.
■ If a red line appears in the judgment display part: positive
A pregnancy reaction has been detected. There is a possibility of pregnancy. Please consult a doctor as soon as possible.
Even if faint, if a vertical line appears in the judgment display part, it is positive.
■ If no red line appears in the judgment display part: negative
No pregnancy reaction was detected in this test. However, if your period does not start afterward, please re-test or consult a doctor.
*The actual shape of the line may differ from the example described in the instructions.

【Precautions related to usage】
■ Please pay attention to the following when using.
［Urine collection precautions］
● Do not use heavily cloudy urine, urine with foreign objects, or blood for testing.
［Timing precautions］
● Be careful not to mistake the timing of testing due to miscalculations of the expected period.
［Operational procedure precautions］
● Perform the test promptly after collecting urine. Leaving urine for a long time may change the test results.
● Follow the prescribed procedure correctly.
［Result interpretation precautions］
● Observe the judgment window to interpret results.
● When interpreting, pay attention to the following.
(1) Do not interpret before a red line appears in the end display part.
(2) If a red line appears in the judgment display part, even if faint, it is positive.
(3) A temporary horizontal line parallel to the check stick may appear in the judgment window during the test, but this is due to the flowing red reagent and is unrelated to the result. Over time, this horizontal line will disappear. The judgment line appears as a vertical line perpendicular to the check stick in the judgment display part.
(4) Depending on how urine is applied, it may take some time. If more than 10 minutes have passed after applying urine and no red line appears in the judgment display part, there may have been an operational mistake (such as insufficient urine). Please repeat the test with another check stick.
In addition to pregnancy, the following conditions may also result in a positive test.
○ Menopause
○ Tumors producing hCG (such as choriocarcinoma)
○ Receiving gonadotropin treatments or similar medications
○ Conditions such as severe diabetes, proteinuria, hematuria, etc.
Even if your period does not occur as scheduled, the following conditions may cause a negative result.
○ Irregular menstrual cycles
○ Miscalculations of days due to misunderstanding of the cycle
○ Early pregnancy with insufficient hCG in urine
○ Abnormal pregnancy (such as ectopic pregnancy)
○ Fetal abnormalities (such as fetal death, missed miscarriage)
○ Excessive secretion of hCG due to molar pregnancy, etc.


▼Precautions for use
■ Consult a doctor if needed
1. Consult a doctor before use if you are:
Undergoing infertility treatment.
2. Even if the result is negative, if your period does not start afterward, please re-test or consult a doctor.
Other precautions
■ Timing for testing
● For regular menstrual cycles
This test can be performed approximately one week after the expected date of menstruation. However, in early pregnancy, hCG levels in urine may be very low in some cases, leading to false negatives or unclear results. If such results occur and about a week passes without your period starting, please re-test or consult a doctor.
● For irregular menstrual cycles
If your cycle is irregular, estimate the expected date based on your last cycle and test approximately one week after that date. If your period does not start afterward, re-test or consult a doctor.
■ Other precautions
When disposing of the used test, dispose of it as urine-contaminated waste or plastic waste according to local regulations.


▼Contraindications
■ Things you should not do
● Do not make a definitive diagnosis of pregnancy based solely on the test result.
○ If the result is positive, pregnancy is possible, but you cannot determine if it is a normal pregnancy, so please see a doctor as soon as possible.
○ A confirmed pregnancy diagnosis is made by a doctor based on medical history, ultrasound, and other comprehensive assessments.
