What is the HCG hormone and what do HCG levels mean during pregnancy?

HCG is an essential hormone that you can have measured to learn more about your pregnancy. Want to have your HCG levels tested? Check out our HCG blood test and get insight into your health.

HCG stands for human chorionic gonadotropin, a hormone produced during the early stages of pregnancy. The hormone is produced by the cells that form the placenta and plays an important role in supporting pregnancy. HCG keeps the endometrium intact and stimulates the production of other hormones, such as progesterone, which are essential for a healthy pregnancy.

How is HCG measured?

HCG can be measured through blood or urine. A blood test provides the most accurate information about HCG levels because it can determine the exact amount of the hormone in the blood. A urine test, such as a pregnancy test, only detects whether HCG is present.

You can request an HCG test through our website, with blood collection at an ISO-certified laboratory. For more information, check out our HCG blood test or our HCG urine test.

HCG levels during pregnancy

HCG levels vary depending on how many weeks you are pregnant. Below is an overview:

• Week 3: 6 - 72 U/L
• Week 4: 10 - 750 U/L
• Week 5: 217 - 71,738 U/L
• Week 6: 158 - 31,795 U/L
• Week 7: 3,697 - 163,563 U/L
• Week 8: 32,065 - 149,571 U/L

This shows that HCG levels rise rapidly during the early weeks of pregnancy. However, the exact value can vary from person to person. Below is an example of an anonymous HCG test result:

Sample results:

• Result: 28,523 U/L
• Pregnancy week: Probably week 6 or 7 (reference: 158 - 163.563 U/L).

What can you do with the results?

1. Confirm pregnancy: An elevated HCG level confirms a pregnancy.
2. Determining gestational age: Based on the value, the estimated gestational age can be determined.
3. Detection of abnormalities: Too low or too high HCG levels can indicate possible complications, such as an ectopic pregnancy or multiple pregnancy.

In case of an abnormal value, you can consult with your doctor or gynecologist for further investigation.

Conclusion

HCG is an essential hormone that you can have measured to learn more about your pregnancy. Want to have your HCG levels tested? Check out our HCG blood test and get insight into your health.

Who could have HCG tested outside of pregnancy?

Although HCG is usually tested to confirm pregnancy, there are situations in which it makes sense to measure the hormone in non-pregnant individuals. Here are some examples:

1. Diagnostics of certain medical conditions

HCG can be found in the blood in some medical conditions, such as:

• Tumors: Some tumors, such as testicular or ovarian tumors, can produce HCG. Elevated HCG levels in non-pregnant individuals may be an indication of a possible malignant tumor.
• Trophoblast diseases: These rare conditions, such as mola pregnancy (mola hydatidosa), can cause HCG production.

In these cases, the test is used as a diagnostic tool or to monitor the effect of treatment.

2. Bodybuilders and athletes

Bodybuilders sometimes use HCG in specific situations, usually in combination with anabolic steroids. Anabolic steroids can suppress the natural production of testosterone, which can lead to testicular shrinkage and reduced fertility. HCG is sometimes used to:

• Stimulate natural testosterone production: HCG mimics the action of luteinizing hormone (LH), which stimulates the testes to produce testosterone again.
• Reduce side effects of steroid use: HCG may help restore the normal function of the gonads after a course of steroids.

Please note that using HCG in this context is not without risk and can cause serious health problems, including hormonal imbalance.

3. Infertility treatments

HCG is also medically prescribed in fertility treatments because it can stimulate ovulation in women or promote sperm production in men.

Why test HCG if you are not pregnant?

An HCG test can provide insight into:

• Unexplained symptoms: Elevated HCG levels without pregnancy require further investigation.
• Monitoring treatments: For example, in cancer therapies or fertility treatments.
• Recovery from steroid use: Although not recommended, some people use HCG tests to monitor the effect of HCG use on their hormone balance.

Conclusion

HCG testing is not only valuable during pregnancy, but can also provide important information in other situations, such as when diagnosing medical conditions or specific hormonal therapies. It is important to always do this under medical supervision. Want to learn more about HCG testing? Check out our HCG blood test for more information.

Here is an overview of related tests of Blood Value Testing that you can consider if you choose to have an intravenous blood draw. These tests are relevant depending on the context and purpose of the HCG test:

Related studies in HCG testing

1. Beta-HCG blood test for women

• What for.
  This test is often used to confirm a pregnancy, determine gestational age or to see if HCG levels are within a normal range. It is also useful in detecting complications such as ectopic pregnancy or trophoblast disease.
• Related tests:
• Progesterone determination: This hormone supports a healthy pregnancy. Measuring progesterone can provide additional information about the quality of the pregnancy.
• Total Pregnancy Monitoring Package: A combination of tests such as HCG, progesterone and sometimes thyroid hormones, to get a broader picture of the pregnancy.
• Why combine.
  A single blood draw can test several hormones at once, saving time and cost.

2. Beta-HCG blood test for men

• What for.
  In men, HCG testing is used to detect abnormalities, such as HCG-producing tumors (for example, testis or germ cell tumors).
• Related tests:
• Testosterone and free testosterone: For a complete picture of hormonal balance.
• LH (Luteinizing Hormone): This hormone stimulates the production of testosterone. An imbalance between LH and HCG may indicate specific disorders.
• AFP (alpha-fetoprotein) and LDH: These markers are often tested together in the evaluation of germ cell tumors.
• Why combine?
  A combined examination can provide a more accurate picture of the cause of any symptoms, such as fatigue, hormonal imbalance or tumors.

3. HCG urine test

• What for.
  This test is primarily used at home for pregnancy detection. It provides a quick, non-invasive method to detect the presence of HCG, but does not give exact values like a blood test.
• Related tests:
• Beta-HCG blood test: If the urine test is positive, you can have the exact HCG value determined via a blood test to estimate the gestational age or detect abnormalities.
• Pregnancy test kit: Combination of urine and blood tests for complete confirmation and analysis.
• Why combine?
  A urine test can serve as a first step, but a blood test can be done for more certainty or for abnormal results.

Why combine multiple tests in an intravenous blood draw?

1. Efficiency: In one blood draw, you can test multiple markers at the same time. This saves time and inconvenience.
2. Cost savings: Multiple tests in one collection are often more economical than separate blood draws.
3. Complete picture: Combinations such as HCG, progesterone, LH, and testosterone offer a broader understanding of hormonal or medical situations.

Recommended combinations based on objectives:

• Pregnancy-related studies:
  Combine HCG with progesterone and thyroid levels to monitor a healthy pregnancy.
• Tumor monitoring (men):
  Combine HCG with AFP, LDH and testosterone for comprehensive assessment of germ cell tumors.
• Hormonal imbalance:
  In addition to HCG, test for LH, FSH, and prolactin to gain insight into possible hormonal causes of symptoms.
