Pregnancy Test Strip

The First Vue HCG Urine pregnancy test measures the presence of the hormone human Chorionic Gonadotropin (HCG) in human urine for early detection of pregnancy. The concentration of HCG in a non-pregnant woman is usually 5mIU. At the time of the missed period the concentration rises to about 100mIU. The test is sensitive to 20mIU of HCG and is capable of detecting pregnancy as early as 7-10 days after conception. We do however recommend that you wait until the first day after your missed period to get a reliable result.

USING THE TEST

Pregnancy test strips are easy to use. Just follow these simple steps:

Collect a Urine sample in a clean dry container.

Open the sealed pouch and remove the strip.

Put the test strip vertically into the urine sample making sure that the arrows are pointing down. Do not allow the urine level to go above the max line marked on the strip.

Leave the test strip in the urine sample for 10 seconds.

Take the strip out, lay it flat and read the result within 5 minutes. For the first few seconds after wetting you should see the liquid moving up the test area causing it to go light pink. As the pink fades the control line will appear as a strong line and the test line if present will appear below this.

READING THE RESULT

POSITIVE RESULT

If two coloured lines appear on the test strip, you are pregnant. One line may appear lighter than the other, but they will both be the same thickness. A faint line is more likely to occur when you are testing early and your hCG levels are low. See Questions 5 and 7 in the frequently asked questions.

NEGATIVE RESULT

If only one coloured line appears on the test strip this is a negative result and you are either not pregnant or you may have tested too early. If you are unsure repeat the test in 48 hours with a new test strip. See Questions 6 and 7 in the frequently asked questions.

INVALID RESULT

If no lines appear anywhere on the test strip or if only the test line appears, the test has not worked properly and is invalid. This is usually due to the strip not being wet enough. Repeat the test with a new test strip ensuring that the strip is immersed in the urine sample for the full 10 seconds. See Question 4 in the frequently asked questions.

 

FREQUENTLY ASKED QUESTIONS

How does the First Vue pregnancy test work?

In a woman who is not pregnant the hormone hCG (Human Chorionic Gonadotropin) is normally present in urine at very low levels (typically 5mIU/ml). When you are pregnant the body produces much more of this hormone. At the time of the first missed period the level of hormone is detectable by this test. Our test detects hCG in urine at a level of 20mIU/ml.

When can I do the test?

You can test as early as 4 days before the expected date of your period. If you are testing early we recommend that you use the first urine of the day as it contains the highest level of hormone in a day. If you are testing from the day of your missed period you can use urine from any time of the day.

How accurate is the First Vue pregnancy test?

In laboratory tests, First Vue pregnancy test strips have been shown to be over 99% accurate when used on the day of your missed period.

What do I do if my test is invalid?

If no lines appear anywhere on the test strip or if only the test line appears, the test has not worked properly and is invalid. This is usually due to the strip not being wet enough. Repeat the test with a new test strip ensuring that the strip is immersed in the urine sample for the full 10 seconds.

What do I do if my test is positive (Pregnant)?

A positive test result shows that hCG has been detected in your urine at a level above 20mIU/ml. You should talk to your Doctor who can tell you what steps you should take next.

What do I do if my test is negative (Not pregnant)?

You may not be pregnant or the level of hCG may not yet be high enough to be detected or you may have miscalculated the day your period was due. If you tested early, test again in 48 hours with a new test. If your period is overdue, test again in 72 hours with a new test. If this retest gives you a not pregnant result and you have still not had your period, see your doctor.

What do I do if I am unsure of my result?

For your result to be positive (Pregnant) you should see 2 lines. The control line should be a strong pink coloured line. The test line may look the same as the control line (Diagram A) or it may be fainter than the control line (Diagram B). In both cases it will be the same thickness as the control line. If you are unsure, wait 48 hours and retest with a new test strip.

Can any medication or medical conditions affect the result?

Testing too soon after using fertility drugs that contain hCG can give misleading results. If you have recently stopped taking hormonal contraception or are using fertility treatments such as clomiphene citrate, your periods may be irregular leading you to test too early.

If you have recently been pregnant (even if not carried to full term) you may get a false pregnant result. Ectopic pregnancy, ovarian cysts, menopause and some very rare medical conditions may give misleading results.

If you have a pregnant result it is possible that you later find that you are not pregnant due to loss of the pregnancy in the early stages. Some women who are more than 6 weeks pregnant may get misleading results due to high hCG levels (2 faint lines due to the hook effect).

If you get unexpected results you should talk about them with your doctor.
