written by: Lashan Clarke•edited by: lrohner•updated: 2/28/2011

There are quite a number of recommended blood tests after perinatal loss, also known as miscarriage or stillbirth. These tests, known as recurrent pregnancy loss testing, can be used to determine what the cause might be for the woman to not be able to sustain a pregnancy.

    Elevated Sugar Levels

    Some women may have a miscarriage or stillbirth due to an elevated blood glucose levels. The same fasting blood glucose test for diabetes is administered to women and is a recommended lab test after perinatal loss.

    In some instances, women who experience a miscarriage may also suffer from resistance to insulin at the receptor level. Since this hormone is used to reduce blood sugar levels, a laboratory test is ordered to determine the level of the hormone insulin and the blood glucose level.

    A physician may decide the glucose tolerance test which can measure the amount of insulin resistance and detect increased glucose levels.

    Test For Progesterone Levels

    One of the main tests for women who have suffered repeated perinatal loss is a test for levels of female hormones that sustain a pregnancy. One of the recommended lab tests after perinatal loss is the blood serum progesterone level. This is a test for the level of the hormone progesterone and the level should be above 10 ng/ml of blood. This is a useful tests and replacement levels of progesterone can be restored based on cause of the decrease in hormone.

    Genetic Testing

    Genetic testing is one of the recommended lab tests after perinatal loss. This can be done on the parents to determine if they are carriers of any genetic diseases. If both parents are carriers of a gene that produces a genetic defect in the child, then a miscarriage may occur. In some genetic diseases, only one parent will need to have the gene mutation for the baby to inherit. Any child conceive may not be able to grow to full term if there is a genetic disease present. In some instances, the parents can be carriers of a mutation that does not produce any symptoms in them, but a fetus is not able to survive to full term.

    Autoimmune Testing

    This blood test is used to determine if the mother has develop auto-immune anti-bodies to fetal tissue. This can be antibodies as a result of the Rh factor on the red blood cells in which the mother’s blood and the baby’s blood were incompatible. In some instances the mother may have an undetected or untreated autoimmune disease. This can affect a woman’s ability to sustain a pregnancy.

    Thyroid Function Tests

    Some women who have untreated thyroid disease in which the thyroid hormone is low, may suffer from a decreased ability to sustain a viable birth. The baby can have fetal malformations, numerous miscarriages and a stillbirth. In some cases, babies can have a low IQ if their mother has untreated hypothyroidism.

    Blood Infections

    Certain blood infections can also cause a miscarriage. Infections such as Rubella or Chlamydia can affect a woman’s ability to carry a baby full-term. These infections would have developed numerous problems in the fetal organs proving fatal for the fetus. Thus the mother will have to be treated for the infection.
