Further testing Throughout the second trimester

Further testing Throughout the second trimester

As well as your regular checkup, you may have additional tests during your second trimester, based upon any health risks or complications that develop. Some evaluations include:


Ultrasound is becoming a vital instrument for the test of your baby while pregnant. They are safe for you and your baby, and they are typically a much-anticipated chance to receive a sneak peek of your candy babe.

Most have an ultrasound at the first trimester to verify pregnancy. Some will wait till the next trimester should they have a minimal risk for complications.

Additionally, if the first-trimester rectal examination agreed with a menstrual relationship, the period of the menstrual period, the ultrasound will delay until the next trimester.

Another trimester ultrasound may confirm or alter the menstrual relationship and your pregnancy period to over 10 to 14 days. Another trimester ultrasound may also have the ability to check the fetal body, the placenta, and the amniotic fluid.

While an ultrasound at the second trimester can provide a lot of information, it will have limitations. Some real problems are more comfortable to view than others, and a few can not be identified before birth.

By way of instance, excess fluid buildup in the brain (hydrocephalus), can usually be diagnosed with ultrasound, but tiny flaws in the heart frequently go unnoticed before arrival.

Triple screen test

At the second trimester, many folks under the age of 35 are given a triple screen test. That is also sometimes called"multiple marker screening" or even"AFP plus." Throughout the evaluation, the mother's blood has been analyzed for three materials.

All these are:

  • AFP that is a protein produced by your infant

  • HCG, which is a hormone that is produced from the placenta

  • Estriol, which is a Kind of estrogen produced by both placenta and infant

  • Screening tests look for abnormal levels of those substances. The evaluation is usually awarded between 15 and 22 weeks of pregnancy. The very best time for the exam is between 16 and 18 weeks.

  • The triple screen tests can detect fetal abnormalities such as Down syndrome, trisomy 18 syndrome, and spina bifida.

  • Abnormal triple screen test outcomes do not necessarily mean there's something wrong. On the contrary, it might signal the risk of a complication, and additional testing ought to be accomplished.

  • For insecure pregnancies, if a triple screen test comes back with strange results, your meddo might recommend additional testing. Sometimes, amniocentesis or chorionic villus sampling may be carried out.

These evaluations are more exact than the triple screen test but have a higher chance of complications. Ultrasounds are also occasionally utilized to search for conditions that might result in abnormal outcomes.

Cell-free oesophagal DNA evaluation

A cell-free oesophagal DNA (cffDNA) test might be used to evaluate your child's risk of getting a chromosomal disease. This is a more recent evaluation, usually offered to individuals with pregnancies at higher risk for trisomy 13, 18, or 21.

The American College of Gynecologists (ACOG) notes this evaluation, such as the triple screen test, is employed as a screening rather than as a diagnostic instrument. To put it differently, in case you've got a favourable cffDNA evaluation, you are going to require a follow-up diagnostic evaluation to confirm a chromosomal abnormality on your infant.

Cell-free fetal DNA is a hereditary substance released by the placenta. It may be found in your blood. It reveals the hereditary makeup of your infant and may detect chromosomal disorders.

Though the cffDNA evaluation is much more exact in analyzing chromosomal abnormalities, it is still suggested that pregnant men and women receive the triple screen test. The triple screen test assesses the bloodstream to get both chromosomal abnormalities and neural tube defects.


Contrary to the triple screen tests, amniocentesis can provide a definite identification.

In this procedure, your meddo is going to take a sample of your amniotic fluid by inserting a needle through your skin and to your amniotic sac. They will assess your amniotic fluid for any chromosomal and genetic abnormalities in your baby.

Amniocentesis is considered an invasive procedure. It takes a small risk of losing the pregnancy. The choice to receive one is a private option. It is only used if the advantages of the evaluation results outweigh the dangers of performing the evaluation.

Amniocentesis will provide you with advice that you can use to make conclusions or to change the course of your pregnancy. As an instance, if understanding that your baby has Down syndrome wouldn't change the course of this pregnancy, amniocentesis might not help you.

Additionally, in case your meddo discovers an ultrasound indicates a disease, you might decide against amniocentesis. But, ultrasound results won't necessarily be accurate since they do not examine the fetal chromosome. Amniocentesis provides a much more definite identification.

One-hour sugar tolerance test

ACOG recommends that pregnant individuals be screened for gestational diabetes utilizing a 1-hour oral glucose tolerance test.

With this evaluation, you will need to drink a sugar solution, usually containing 50 g of sugar. After an hour, you will have your blood drawn to test your glucose level.

If your sugar test is abnormal, your health care provider will suggest a 3-hour sugar tolerance test. This is much like the 1-hour test. Your blood will be drawn after waiting.

Gestational diabetes causes the human body to have difficulty controlling the quantity of sugar in the blood. Controlling your blood glucose level is essential for a healthy delivery.

When you've got gestational diabetes, you might want to create modifications in your diet and workout habits, or even take drugs. Gestational diabetes usually goes away once you have your baby.

Other evaluations

Based upon Your obstetrical history and your current health, your meddo can perform additional evaluations for:

  • blood count

  • platelet count

  • RPR, a rapid plasma reagin test for syphilis

  • Sexually transmitted diseases (STIs)

  • bacterial vaginosis

A number of the tests require a blood flow, and many others call for a urine sample. Your physician may also have to swab your cheek, vagina, or cervix to check for infections.

Blood and platelet evaluations can determine a weak immune system or blood clotting problems, which may complicate pregnancy and childbirth.

STIs and other bacterial diseases may also lead to problems for you and your infant. If they are detected early, you can treat them until your baby is born.

Talking to your Physician

If your health care provider finds an abnormality on your infant, you will have a lot of chance to find out more about your physician's status or pros. Your physician may recommend you talk to a genetic counsellor to find out about the problem's origin, therapy, risk of recurrence, prognosis, and avoidance.

Your health care provider will talk about options for treating your pregnancy. If pregnancy termination is an alternative, your physician will not let you know what choice to make.

If termination isn't an option on account of your personal beliefs, then the advice your physician shares with you will help you handle your pregnancy. Sometimes, for example, with neural tube defects, the result may improve with cesarean delivery.
