Miscarriage Blood Test

What is Miscarriage?

Miscarriage is the spontaneous loss of a pregnancy before 20 weeks of gestation, affecting 10-20% of known pregnancies. Low progesterone levels are a common hormonal cause that prevents the uterine lining from properly supporting embryo development. The Progesterone blood test is the most important test for assessing hormonal factors that contribute to miscarriage risk.

What causes miscarriage?

Miscarriage is caused by chromosomal abnormalities in about 50-70% of cases, where the embryo develops with genetic errors incompatible with life. Hormonal imbalances, particularly low progesterone levels produced by the corpus luteum, can prevent the uterine lining from adequately supporting the pregnancy. Other causes include uterine structural problems, maternal health conditions like uncontrolled diabetes or thyroid disorders, immune system issues, and severe infections that affect the developing pregnancy.

What is the best test for miscarriage?

The Progesterone blood test is the most important test for assessing miscarriage risk because it measures the hormone essential for maintaining the uterine lining and supporting early pregnancy. Progesterone levels below 10 ng/mL in early pregnancy indicate insufficient hormonal support, which can lead to pregnancy loss. This test helps healthcare providers identify women who might benefit from progesterone supplementation and understand whether hormonal factors are contributing to recurrent pregnancy loss. While ultrasound confirms miscarriage diagnosis, progesterone testing provides critical insight into preventable hormonal causes.

When should I get tested for miscarriage?

You should get tested if you experience vaginal bleeding or spotting during pregnancy, especially when accompanied by cramping or pelvic pain. Women with a history of recurrent miscarriages (two or more pregnancy losses) should get progesterone testing in early pregnancy to identify treatable hormonal deficiencies. Testing is also important if you notice pregnancy symptoms suddenly disappearing, have been diagnosed with luteal phase defect, or are planning pregnancy after previous losses to establish baseline hormone levels.

What are the symptoms of miscarriage?
Miscarriage symptoms include vaginal bleeding that ranges from light spotting to heavy bleeding with clots, often accompanied by cramping or abdominal pain that feels like menstrual cramps. You might notice the sudden disappearance of pregnancy symptoms like breast tenderness and nausea, along with passing tissue or clot-like material from the vagina. Some women experience back pain, weakness, or fever, though early miscarriages can sometimes occur with minimal symptoms, detected only during ultrasound examination.
Who is at risk for miscarriage?
Women over age 35 face increased miscarriage risk, with rates rising to 20% by age 35 and over 40% after age 40 due to chromosomal abnormalities in eggs. Those with a history of two or more previous miscarriages, chronic health conditions like diabetes or thyroid disorders, uterine abnormalities, or polycystic ovary syndrome have higher risk. Lifestyle factors including smoking, excessive alcohol consumption, drug use, obesity, and exposure to environmental toxins also increase the likelihood of pregnancy loss.
What happens if miscarriage is left untreated?
Incomplete miscarriage, where pregnancy tissue remains in the uterus, can lead to severe complications including heavy bleeding, life-threatening hemorrhage, and infection of the uterine lining called endometritis. Retained tissue can cause fever, foul-smelling discharge, prolonged bleeding, and in severe cases, sepsis requiring emergency medical intervention. Without proper monitoring and treatment, complications can affect future fertility and cause scarring of the uterus, making it crucial to receive medical care for proper management and emotional support during pregnancy loss.
Can miscarriage be diagnosed with a blood test?
Blood tests alone cannot definitively diagnose miscarriage, but they provide essential information about pregnancy viability and hormonal support. Serial measurements of human chorionic gonadotropin (hCG) that fail to double every 48-72 hours in early pregnancy suggest potential miscarriage, while progesterone levels below 10 ng/mL indicate inadequate hormonal support. Diagnosis requires combining blood test results with ultrasound imaging to visualize the pregnancy and confirm whether the embryo has a heartbeat or if pregnancy tissue is still present in the uterus.
How is miscarriage treated?
Miscarriage treatment depends on whether the pregnancy tissue passes completely on its own, with expectant management allowing natural passage over 1-2 weeks while monitoring for complications. Medical management uses medications like misoprostol to help the uterus expel remaining tissue, while surgical treatment through dilation and curettage (D&C) removes tissue immediately when bleeding is heavy or infection risk is high. Women with low progesterone in early pregnancy may receive progesterone supplementation to prevent miscarriage, and emotional support including counseling is an important component of comprehensive care following pregnancy loss.
How can I prevent miscarriage?
While many miscarriages caused by chromosomal abnormalities cannot be prevented, maintaining optimal health before and during pregnancy reduces preventable risks. Take prenatal vitamins with folic acid starting before conception, manage chronic conditions like diabetes and thyroid disease, maintain a healthy weight, and avoid smoking, alcohol, and recreational drugs. Progesterone supplementation may prevent miscarriage in women with documented deficiency, and limiting caffeine intake to less than 200mg daily can help. Reduce exposure to environmental toxins and infections, and seek early prenatal care to monitor pregnancy health and address concerns promptly.
What can I do at home after miscarriage?
After miscarriage, rest as much as possible and use sanitary pads rather than tampons to monitor bleeding while reducing infection risk. Take over-the-counter pain relievers like ibuprofen for cramping, apply a heating pad to your abdomen for comfort, and stay well-hydrated. Avoid sexual intercourse, douching, and strenuous exercise for at least two weeks or until bleeding stops. Allow yourself time to grieve emotionally, seek support from loved ones or support groups, and contact your healthcare provider immediately if you experience fever, severe pain, heavy bleeding soaking through more than two pads per hour, or foul-smelling discharge.
