no matter how light,
you have hCG present in urine.
Aimstick is sensitive to low levels of hCG
We've had positive results as early as 8dpo
but it's best to wait until 10-12 dpo
Test is quite stable but try to keep at room temperature.
INTENDED USE
TTC eHPT is a rapid dipstick test for the qualitative determination of human Chorionic Gonadotropin (hCG) in urine to aid in the early detection of pregnancy.
SUMMARY & EXPLANATION
Human Chorionic Gonadotropin (hCG) is a glycoprotein hormone which is secreted by the developing placenta after fertilization. The appearance and increased levels of hCG provide an excellent indicator of pregnancy. The hCG hormone doubles approximately every 2.2 days during the first trimester. Detectable levels start at 5 mlU/mL during the first week of gestation and rise to 100,000 mlU/mL at 2 to 3 months. Miscarriage may be associated with a slow rise in hCG levels. During the 2nd and 3rd trimesters, hCG levels decline 10% to 15% from peak concentrations.
EXPECTED VALUES
Healthy pregnant women should have hCG present. The amount will vary greatly with gestational age and between women. First morning urine specimens approximate serum hCG levels which reach 5 to 50 mlU/mL within 1 week of gestational age. TTC eHPT can detect pregnancy as early as 1 day after a missed menses. Since levels of 25 mIU/mL of hCG have been observed as early as 3 to 4 days after implantation, hCG may be detected before a first missed menses.
SPECIMEN COLLECTION AND PREPARATION
Urine specimens should be collected in a clean, dry container. Randomly collected specimens can be used. However, the first morning urine generally contains the highest concentration of hCG.
Specimen Storage - Specimens may be refrigerated (2� - 8�C) and stored up to 72 hours prior to testing. If specimens are refrigerated, they must be brought to room temperature before testing.
DIRECTIONS FOR USE
If you have placed specimen in refrigerator to preserve until testing, please allow specimen and/or controls to reach room temperature (20�C to 30�C) prior to testing.
1. Remove the test strip from the sealed pouch.
2. Hold the test strip in a vertical position with the arrows pointing downward. Lower the test strip into the urine specimen. Do not immerse the test strip beyond the "Stop Line".
3. Hold the test strip in the urine for at least 5 seconds. Remove and place on a non-absorbent level surface.
4. Read results after 3 minutes. Do not interpret results after 30 minutes
INTERPRETATION OF RESULTS
Negative Results
The test is negative if only one colored line appears in the Control Zone.
Positive Results
The test is positive if two colored lines appear. One colored line will appear in the Specimen Zone and one in the Control Zone. This indicates the specimen contains detectable levels of hCG. Any colored line in the Specimen Zone should be considered positive. Specimens containing levels of hCG below 20 mlU/mL may show color development over time. The colored line in the Control Zone may be lighter or darker in color than the line in the Specimen Zone.
Invalid Results
The test is invalid if a colored line fails to appear in the Control Zone, even if a colored line appears in the Specimen Zone. This can be caused by not immersing the test strip for at least 5 seconds or by immersing it beyond the "Stop Line". Immerse the test strip for an additional 5 seconds and wait 3 minutes. If this does not work, repeat the test using a new test strip making sure not to immerse beyond the "Stop Line".
A line appearing below the �dipping� arrows (Stop Line) DOES NOT indicate a positive result. You must have a Control Line and a Specimen Line (or 2 lines) appearing in the same zone or area as shown below for a positive result.
The following potentially interfering substances were added to hCG negative and positive urine samples. None of the substances at the concentration tested interfered in the test.
Acetaminophen ~ 20 mg/dl
Acetylsalicylic Acid ~ 20 mg/dl
Ascorbic Acid ~ 20 mg/dl
Atropine ~ 20 mg/dl
Caffeine ~ 20 mg/dl
Gentisic Acid ~ 20 mg/dl
Glucose ~ 2 g/dl
Hemoglobin ~ 1 mg/dl

I
noticed lots of ladies are asking questions about proper hCG levels.
I
thought it might be a good idea to post the ranges.
Here
they are:
|
Weeks since last AF |
Amount of HCG |
|
3 |
5 - 50 miu/ml |
|
4 |
10 - 425 |
|
5 |
19 - 7,340 |
|
6 |
1,080 - 56,500 |
|
7-8 |
7,650 - 229,000 |
|
9-12 |
25,700 - 288,000 |
Of
course, everyone is different and their level might be slightly
different
than these ranges, but it might help calm some fears
to have
something to compare with.
