Diagnostic Human Chorionic Gonadotropin HCG Test Kits
Intended use of HCG test kits:
Chorionic Gonadotropin (HCG) is a glycoprotein hormone secreted by
the placental chorionic cells after a woman's fertilized egg is
implanted. It can enter the blood and urine through the blood
circulation. HCG can be detected in serum or urine within 1 week of
normal pregnancy. The concentration of HCG rises rapidly, until the
first menopause, the concentration usually exceeds 100mIU/ml, and
by 10-12 gestational weeks, the HCG concentration reaches
15000-200000mIU/ml Pinnacle. In general, the urine HCG of
non-pregnant women is often less than 25mIU/ml. Therefore, the
detection of HCG is an important indicator for clinical diagnosis
of pregnancy.
Human chorionic gonadotropin (HCG) rapid detection kit uses
colloidal gold technology and immunochromatography technology to
detect HCG in human urine, which is used for clinical auxiliary
diagnosis of pregnancy.
Detection principle:
The product uses the double antibody sandwich method and the
principle of colloidal gold immunochromatography to qualitatively
detect HCG in urine.
Packaging composition:
HCG test paper (100 servings): single serving in aluminum foil bag.
Instructions for use (1 copy/box).
Sample collection and processing:
Sample collection container: clean and pollution-free plastic
container, or disposable container, used to collect urine samples.
Timer: used to time the detection.
Urine samples must be collected in clean, dry plastic or glass
containers. Urine can be collected at any time of the day. However,
the first morning urine of the day usually contains the highest
concentration of HCG. The storage time of urine samples frozen at
2°C-8°C does not exceed 72 hours. The temperature of the frozen
urine sample should be equilibrated to room temperature before
testing.
Detection steps:
1. The test carton should be used within 1 hour after tearing; if
it is in an environment with more than 30°C or high humidity, it
should be used as soon as possible.
2. Tear the cut of the aluminum foil bag, take out the test pen,
take out the pen cap, let the urine drip on the urine suction hole
for 5 seconds when urinating, cover the pen cap, and lay the test
pen flat.
3. Wait for the red band to appear. The result is interpreted in
3-5 minutes, and the judgment is invalid after 10 minutes.
Positive: A red line appears at the position of the detection line
and the quality control line.
Negative: Only a red line appears at the position of the quality
control line.
Invalid: No red line appears at the position of the quality control
line, indicating that the result is invalid and should be tried
again.
Matters needing attention:
1. There is no color band on the quality control line and the test
line, indicating that a test error should be retryed; when the HCG
concentration is high, the test line is obvious, and the control
line may become weak, which is a normal result;
2. If the subject is still suspected of being pregnant, and the
urine test is negative, the morning urine can be collected again
after 48 to 72 hours;
3. Patients with uterine tumors, hydatidiform moles or menopause
may have a positive result due to the high content of HCG in the
urine
4. The final result should be determined by the clinician's
comprehensive analysis of all clinical indexes and laboratory test
results.
5. Some immune interference substances, such as those used in
antibody therapy, will invalidate the test results.
6. Storage: Store at 4~30℃ and avoid light. Do not freeze. Use
within the validity period.
7. Validity period: 24 months
