- used to visualize a fetus during routine and emergency prenatal care.First trimester ultrasound is often done using a vaginal approach. Pelvic ultrasound is used during second and third trimester.
Obstetric ultrasound is primarily used to:
* Date the pregnancy (gestational age)
* Confirm fetal viability
* Determine location of fetus, intrauterine vs ectopic
* Check the location of the placenta in relation to the cervix
* Check for the number of fetuses (multiple pregnancy)
* Check for major physical abnormalities.
* Assess fetal growth (for evidence of intrauterine growth restriction (IUGR))
* Check for fetal movement and heartbeat. (biophysical)
* Determine the sex of the baby
2. Urinalysis
- reveal diseases that have gone unnoticed because they do not produce striking signs or symptoms. Example is Urinary tract infections for pregnant women.
- Physical (color, reaction, transparency, quantity, specific gravity); Chemical (albumin and sugar); Casts; Crystals; Microscopic (Pus cells red blood cells and epithelial cells) and Bacteria are being checked.
3. HBsAG (Hepatitis B surface Antigen)
- A test used to determine if pregnant woman is infected with hepatitis B.
- Negative value is 0.002 and positive value is 3.148
4. Blood Test / Hematology
- To know the blood / Rh type
- For hematology, the following are being checked:
* Leukocyte 5.0-10.0
* Erythrocytes 4.2 – 5.4
* Hemoglobin 11.0 – 15.0
* Hematocrit 37.0 – 47.0
* Thrombocyte 150 – 450
--- Neutrophil 50.00 – 70.00
--- Lymphocyte (P) 20.0 – 40.0
--- Monocyte (P) 0.0 – 7.0
--- Eosinophils (P) 0.00 – 5.00
--- Basophils (P) 0.00 – 1.00
5. Glucose Challenge Test (GCT)
- Blood test used to screen women for diabetes during pregnancy. The test evaluates the body’s ability to metabolize glucose (blood sugar). The test is usually ordered between the 24th and 28th weeks of pregnancy, sometimes earlier.Blood is drawn one hour after the patient drinks a sugary solution. 0 – 140 mg/dL is the normal range.
