Pregnancy Diagnosis: Knowledge Quiz

This article provides information on pregnancy diagnosis methods, helping you understand the signs, how to determine the age of the fetus, and important things to note throughout pregnancy.

Signs of Pregnancy:

• Confirmed signs:

• Fetal heartbeat can be heard

• Fetal movement can be felt

• Ultrasound reveals the fetus

• Unconfirmed signs:

• Positive pregnancy test

Determining the Age of the Fetus:

• Most accurate method: Ultrasound

• Other methods:

• Based on the last menstrual period (for reference only)

• Vaginal examination (measuring the size of the uterus)

• X-ray (not recommended)

Pregnancy Diagnosis Methods:

• Recommended methods:

• Ultrasound

• Fetal heartbeat listening

• Serum β hCG test

• Limited use method: X-ray

Important information:

• Fetal heartbeat can be seen on ultrasound from: 7 weeks after the last menstrual period

• Most common pregnancy test method: Immunological reaction

• To predict the age of the fetus and the due date, people often rely on: The first day of the last menstrual period

• Manifestation on the breast during pregnancy: Haller’s venous network

• Clearly hear the fetal heartbeat with a stethoscope at the age of the fetus: 20-22 weeks

• Accurate way to measure the height of the uterus: Measure from the midpoint of the superior edge of the pubic bone to the midpoint of the bottom of the uterus

• Rate of increase in uterine height each month: 4 cm

• Hormone that determines the presence of pregnancy: hCG

• The ultrasound image of the embryo starts to become clear from: 7 weeks after the last menstrual period

• Average growth rate of the biparietal diameter of the fetus (before week 30): 4 mm per week

• Signs of hydrocephalus on ultrasound (fetus near delivery date): Fetal diameter measured from 110 mm or more

Cases to note:

• 5 days late but ultrasound does not show the amniotic sac: It is advisable to combine hCG quantification and ultrasound again later.

• Late period with nausea: It is necessary to test for hCG and then consult based on the test results.

• 1 month late, prolonged bleeding, ultrasound reveals a mixed echo area in the uterus: May be an incomplete miscarriage.

hCG test:

• Most reliable method: Quantitative serum hCG test by immunoassay
