Check4®-hCG(hl) for Patients

Check4®-hCG(hl) is a urine test that can be used at home to check the outcome of first trimester Termination of Pregnancy (ToP) or miscarriage.

Quick

Check4®-hCG(hl) works quickly, delivering results in under 10 minutes.

Accurate

Check4®-hCG(hl) is very reliable and 99% accurate, when performed correctly.

Easy-to-use

Check4®-hCG(hl) has easy-to-follow instructions, providing reliable and easy-to-interpret results.

How Does the Test Work?

Check4®-hCG(hl) checks urine for a hormone called hCG (human Chorionic Gonadotropin). When a woman becomes pregnant, her body begins to produce hCG, which is excreted in the urine where its concentration rises over time.

If the treatment for Termination of Pregnancy (ToP) has been successful then the hCG concentration levels should drop below 1000 mIU/mL within 10 to 20 days. The Check4®-hCG (hl) test uses a pair of antibodies specifically detecting the hCG hormone in urine to check whether the hormone level is 1000 mIU/mL or greater.

The positive test result means that the treatment for the ToP may not have worked or is not complete.
The negative result means that the ToP is confirmed.

When to Do the Test?

Check4®-hCG(hl) must be performed at a time indicated by your healthcare provider, usually between 10 to 20 days after the first medical abortion drug intake or after first trimester miscarriage.

It is best to do the test first thing in the morning, as urine is more concentrated.

Timing is important!

Don’t test too early  – Your hCG levels could still be high.

Don’t test too late  –  You’ll delay extra care and support if the medicine hasn’t worked.

How to Use the Test?

The video and quick guide below are intended to show you how to use the Check4®-hCG(hl) test. Always ensure you read the full instruction leaflet provided with the test. If the instructions are not followed, the result may not be accurate.

Quick Guide

Before starting to perform the test, please note these important precautions:

  1. Always follow any specific instructions provided by your healthcare professional
  2. Do not use the test after the expiry date or if the packaging is damaged.
  3. To ensure your test results are as accurate as possible, we recommend using your first morning urine and do not drink lots of fluid before performing your test.

Once you have removed the test device from the foil pouch, you are ready to perform the test.

You can either:

A) Hold the absorbent tip in your urine stream for 5-10 seconds. Take care no urine enters the test window.

B) Collect your urine in a clean and dry container and dip the absorbent tip into the urine for at least 5 to 10 seconds in order for it to be completely soaked. Take care no urine enters the test window.

Once completed, replace the cap and lay the test flat on a clean, dry surface with the windows facing up.

Wait for a minimum of 5 minutes and then read your results. Do not read the test after 10 minutes.

Please make sure you have waited for a minimum of 5 minutes to read your results. Do not read the test after 10 minutes.

Positive Result: If two pink lines appear, one in the test window and one in the control window, your test is positive. This could indicate that the termination of pregnancy may not be complete.
Please Note: One line can be darker than the other, and the lines can be any shade of pink-purple.

Negative Result: If only one line appears in the control window, the test is negative, confirming the termination of pregnancy.

Invalid Result: If no lines appear in the control window, the test is invalid. You should retest with a new Check4®-hCG(hl) and a fresh urine sample after 24 hours.

Depending on your results we recommend the following, but please always make sure you follow any specific instructions provided by your healthcare professional:

  • Positive: Consult your healthcare professional immediately.
  • Negative: No further action should be required, but consult your healthcare professional if you have symptoms of pregnancy.
  • Invalid: Retest after 24 hours with a fresh urine sample. Consult your healthcare professional for further assistance.

FAQs

Your Questions, Answered

When a woman becomes pregnant, her body begins to produce a hormone, human Chorionic Gonadotropin (hCG), which is excreted in the urine where its concentration rises over time. The Check4®-hCG (hl) test uses a pair of antibodies specifically detecting the hCG hormone in urine to check whether the hormone level is 1000 mIU/mL (determined against World Health Organisation W.H.O. reference) or greater.

If treatment for Termination of Pregnancy or miscarriage has been successful then the hCG level should drop below 1000 mIU/mL within 10 to 20 days. Check4®-hCG (hl) will not detect hCG levels lower than 1000 mIU/mL while classical pregnancy tests will be positive.

Yes, we recommend testing Check4®-hCG (hl) on the first morning urine that should be more concentrated.

Yes, a high fluids intake may dilute the urine and make the hCG detection more difficult. Abnormal fluids intake is therefore not recommended.

If you are unable to determine whether or not a line is present in the oval test window, repeat the test after 1 day with a new Check4®-hCG (hl) test. If you follow the instructions, you should get accurate results. Certain drugs and medical conditions such as cancer or uterine malignancies inducing high level of hCG or LH secretion may lead to a false positive result.

Yes. A few extra seconds will not affect the results.

No, because the urine sample volume may not be sufficient in order for the test to perform well.

As long as you see a line in each window, the test result is positive.

You must follow the advice given by the medical staff managing you.

If you read the test before 5 minutes, you may not give the test enough time of work, and the test result may not be accurate.

Important: DO NOT INTERPRET the results if 10 minutes have elapsed after having brought the absorbent tip into contact with urine.

The Check4®-hCG (hl) is very accurate and has been used by health care professionals to confirm the success of medical Termination of Pregnancy up to 9 weeks amenorrhea (hospitals and laboratories).

Evaluation reports show the Check4®-hCG (hl) overall correlation is 99%* (CI** 95% [94.21 – 100.0]) of cases, the diagnostic sensitivity of Check4®-hCG (hl) test is 100% (CI 95% [92.45 – 100.0]) and the diagnostic specificity is 98.0% (CI 95% [88.78 – 100.0]) when compared to reference method. No test is perfect and even if the test is negative, you should still contact your health care provider if you have symptoms of pregnancy such as scanty bleeding, no period, tender breasts, feeling sick, and a growing tummy.
* Claimed accuracy is with regard to testing performed on or after the day prescribed by the gynaecologist.

Yes, but Check4®-hCG (hl) is not able to detect very early pregnancies and only shows positive if the hCG hormone is more than 1000 mIU/mL. Other urine tests are usually more sensitive and give a positive result starting from 5 to 25 mIU/mL.
