Triple Marker Test in Pregnancy

  • The Triple Marker Test is a prenatal screening test that measures levels of three substances in the mother's blood: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and estriol (E3).
  • The test is typically performed between 15 and 20 weeks of pregnancy and is used to assess the risk of certain birth defects, chromosomal abnormalities, and other pregnancy-related conditions.
  • Abnormal levels of any of the markers may indicate a higher risk of certain conditions, but further testing and evaluation are usually needed to confirm any potential issues.
  • The test is a non-invasive and relatively safe way to screen for potential issues during pregnancy.

Interesting Facts About Pregnancy

  • Pregnancy typically lasts around 40 weeks from the first day of the last menstrual period.
  • The baby's heart begins to beat around 6 weeks into pregnancy.
  • Pregnant women may experience food cravings, mood swings, and increased blood volume.

  • The blood sample is then sent to a laboratory for analysis.
  • The laboratory technicians analyze the sample for the levels of three substances: alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG), and estriol.
  • The test results are usually available within a few days and are sent to the doctor who ordered the test.
  • The doctor will interpret the results and discuss them with the patient to determine the next steps.

 

Triple Marker Test Result

  • The test provides the level of three substances in the mother's blood, which can indicate the likelihood of certain conditions in the fetus.
  • The normal range of results varies depending on factors such as the gestational age of the fetus, the mother's age, and other individual factors.
  • Abnormal results may indicate a higher risk of certain birth defects, genetic disorders, or chromosomal abnormalities in the fetus. However, it's important to note that abnormal results do not necessarily mean that the fetus has a condition, and further testing may be needed to confirm or rule out a diagnosis.

Low AFP, High hCG, Low E3 Increased risk of Down syndrome or other chromosomal abnormalities
Low AFP, Low hCG, High E3 No established significant increase in risk
High AFP, High hCG, High E3 Increased risk of Down syndrome or other chromosomal abnormalities
High AFP, High hCG, Low E3 Increased risk of placental or fetal abnormalities

It is important to note that abnormal levels of any of these markers may not necessarily indicate a problem with the pregnancy, and further testing or evaluation may be needed to confirm any potential issues.

 

Difference Between Double Marker and Triple Marker Test

Here are some key differences between the Double Marker and Triple Marker tests:

Triple Marker Test Double Marker Test
Done between 14-20 weeks of pregnancy Done between 10-14 weeks of pregnancy
Measures three markers: β-hCG, alpha-fetoprotein (AFP), and unconjugated estriol (uE3) Measures two markers: beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein-A (PAPP-A)
Screens for Down syndrome and neural tube defects Screens for Down syndrome and other chromosomal abnormalities
Provides a risk score for the fetus having Down syndrome and/or neural tube defects Provides a risk score for the fetus having Down syndrome or other chromosomal abnormalities
More accurate than the Double Marker test Less accurate than the Triple Marker test
Generally not followed by another test May be followed by a Triple Marker test if the risk for neural tube defects is still present

Summary

It is important to note that both the Double Marker and Triple Marker tests are screening tests, which means that they provide a risk score for the fetus having a certain condition. These tests are not diagnostic, and further testing may be recommended to confirm a diagnosis.

Triple Marker Test FAQ

What is a Triple Marker Test?

The Triple Marker Test, also known as the Triple Screen Test or the Second Trimester Screen, is a prenatal screening test conducted during the second trimester of pregnancy.

  • It involves measuring the levels of three substances in the maternal blood: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and estriol.
  • The test helps assess the risk of certain chromosomal abnormalities, such as Down syndrome (trisomy 21) and neural tube defects, in the developing fetus.

Why is a Triple Marker Test done?

The Triple Marker Test is performed to screen for the risk of chromosomal abnormalities and neural tube defects in the fetus.

  • It is typically recommended for pregnant women between 15 and 20 weeks of gestation, offering an assessment of the individual's risk for Down syndrome, as well as open neural tube defects like spina bifida.
  • The test results, along with other factors such as maternal age, gestational age, and medical history, can help guide further diagnostic testing or provide information for genetic counseling.

How is a Triple Marker Test performed?

The Triple Marker Test involves a simple blood draw from the pregnant woman.

  • The blood sample is sent to a laboratory, where the levels of AFP, hCG, and estriol are measured.
  • These values, along with maternal age and gestational age, are used to calculate the risk ratio for chromosomal abnormalities and neural tube defects.

How to interpret the results of a Triple Marker Test?

The results of the Triple Marker Test provide an assessment of the individual's risk for chromosomal abnormalities and neural tube defects.

  • Abnormal levels of AFP, hCG, or estriol may indicate an increased risk for certain conditions, such as Down syndrome or neural tube defects.
  • It's important to note that the Triple Marker Test is a screening test and not a diagnostic test.
  • Positive results do not confirm the presence of abnormalities but indicate a higher risk, which may require further diagnostic testing, such as ultrasound, amniocentesis, or genetic counseling for a definitive diagnosis.
  • Consulting with a healthcare professional is essential for understanding the results and determining the appropriate next steps.
