Get-go Things First: Tests to Ostend that Y'all're Significant

All pregnancy tests work by detecting a hormone in your blood or urine that's there only if you lot're pregnant.  This hormone – human chorionic gonadotropin (hCG) – is produced when a fertilized egg implants in your uterus.

There are ii types of pregnancy tests:

• A urine test can exist performed at your doctor's office or with a home pregnancy test
  • Urine tests can normally tell if you're pregnant virtually one week after a missed period

  • Blood tests can find hCG earlier in a pregnancy than urine tests, usually 6 to 8 days subsequently you ovulate

If a dwelling house pregnancy examination shows that yous're pregnant, call your dr. right away.  He or she can use a more sensitive test along with a pelvic test to confirm it.  Plus, seeing your doctor early in your pregnancy helps yous and your baby stay every bit healthy as possible (visit our Prenatal Intendance & Commitment page to acquire more about care during pregnancy).

Routine Tests During Pregnancy

Certain laboratory tests are recommended for all women every bit part of routine prenatal care.  These tests tin aid discover weather that might put yous or your fetus at gamble of complications, and allow for timely handling.

Tests Done in Early on Pregnancy

• Complete Claret Count (CBC) with Differential/Platelet – Measures the numbers of different types of cells that make up your blood to check for anemia, infection and your claret-clotting ability
• Urinalysis and Urine Civilization – Detects urinary tract disease, infection, glucose (high levels may be a sign of diabetes) and poly peptide.
• Hepatitis B – Meaning women with Hepatitis B virus (which infects the liver) tin pass the virus to their babies
• Rubella (German Measles) – Tin cause birth defects if a woman is infected during pregnancy. Your blood is tested to see if you've had a past rubella infection or if you've been vaccinated confronting it.
• HIV – Significant women infected with HIV can be given medication and take other steps that greatly reduce the risk of passing the virus to their babies
• Varicella Zoster V Antibodies (Craven Pox) – This examination is done to detect whether a women is immune to varicella (craven pox).
• Blood Typing – Determines your claret blazon and Rh gene (a protein on the surface of red claret cells). Blood types are either A, B, AB or O, and the Rh cistron is either positive or negative.Problems can occur if a woman is Rh negative and her babe is Rh positive.
• Antibody Screen – If you are Rh negative, your immune arrangement can develop an antibody that attaches to the Rh-positive antigens on your fetus' reddish blood cells, targeting them for destruction.  An antibody screen is used to detect these antibodies. The first Rh-positive infant is unlikely to go sick, but antibodies produced during a first pregnancy will affect future Rh-positive babies
• Sexually Transmitted Illness (STD) Testing – Significant women are screened for syphilis (a test chosen rapid plasma reagin, or RPR) and chlamydia early in pregnancy because these STDs can exist passed to their babies and cause other complications.
• Thyroid Stimulating Hormone (TSH) – Because thyroid problems are associated with pregnancy complications, women are tested to ensure that their thyroid is functioning properly. This is tested in patients with specific family or medical history.

Tests Done Mid-Pregnancy

• Glucose Tolerance Test – This measures the level of glucose (sugar) in your blood; a high level may be a sign of gestational diabetes
• Hemoglobin and Hematocrit – It's not uncommon to develop anemia as your pregnancy progresses, so your blood volition be tested in your late second trimester or early tertiary trimester
• RPR (Syphilis screen #2) – All women receive a second exam to screen for syphilis in their second trimester

Tests Done in Late Pregnancy

• Group B Strep (GBS) Culture – GBS is a type of bacteria that lives in the vagina and rectum. Many women comport GBS without having symptoms, but it can be passed to a babe during birth and cause serious health issues. Antibiotics can be given during labor to help preclude infection of the baby.

Tests to Screen for Birth Defects

Today there are several noninvasive screening tests bachelor to you lot in the starting time and 2d trimesters of pregnancy to assess the chances that your fetus may have a genetic (inherited) disorder and/or birth defects.  If you are at gamble, your doctor volition discuss these optional tests with you.

• Sequential Screen – A two-stage screening that assesses the risk of several chromosomal abnormalities including Down syndrome.  The offset stage (combining ultrasound and blood testing) can be performed between 11 weeks and thirteen weeks and half-dozen days.  The 2d stage (blood testing) can be performed between 15 and 22 weeks.
• Maternal Serum Quad Screen– A maternal blood screening test that looks for 4 specific substances in the blood
• Alpha Fetoprotein (AFP) – This blood test checks the level of AFP in a pregnant woman's claret during the second trimester
• Carrier Screening – Testing that's done to see if you or your partner carry a genetic mutation that could cause a serious inherited disorder (such as cystic fibrosis) in your infant
• Non-invasive prenatal testing (NIPT) – As well called cell complimentary DNA testing (cfDNA), this claret test analyzes fetal Dna circulating in a significant woman'south blood; information technology tin can be performed at x weeks. The American Congress of Ob/Gyn does not recommend NIPT in pregnancies when at that place is more than 1 fetus (twins, triplets, etc…).

It's important to empathize that these screening tests do non diagnose a problem; they only bespeak that further testing (such as amniocentesis or chorionic villus sampling) should exist done.

Considering many of these tests are done in women who are at high take a chance for having a child with a chromosomal aberration or nascence defect, we ofttimes recommend that they undergo genetic counseling to sympathize their options.
