Pregnancy Test

Positive results indicate the presence of hCG hormone, confirming pregnancy. The levels of hCG typically increase rapidly in early pregnancy.

• In cases of a suspected ectopic pregnancy or abnormal pregnancy, the hCG levels may be lower or rise at a slower rate.
• A negative result suggests the absence of detectable hCG hormone, indicating that pregnancy has not occurred or it is too early to detect.

The Double Marker Test is performed to screen for the risk of chromosomal abnormalities in the developing fetus.

• It is typically recommended for pregnant women, particularly those over the age of 35 or with a higher risk based on family history, previous pregnancy complications, or abnormal ultrasound findings.
• The test provides an assessment of the individual's risk of having a baby with Down syndrome or trisomy 18, allowing for further diagnostic testing or genetic counseling, if necessary.

If alpha-fetoprotein (AFP) levels are elevated, it is important to consult with a healthcare professional for further evaluation. The appropriate course of action depends on the context and suspected underlying condition. Additional diagnostic tests, such as imaging studies (ultrasound, CT scan, MRI) or biopsies, may be recommended to investigate the cause of elevated AFP. The specific treatment or management plan will depend on the underlying condition diagnosed and may involve therapies such as surgery, chemotherapy, radiation therapy, or ongoing monitoring and surveillance.

The confirmatory test for Group B strep is the culture test, where a sample from the vagina and rectum is collected and cultured to identify the bacteria. This is usually done around the 35th-37th week of pregnancy.

The first trimester screening typically includes a combination of ultrasound and blood tests. The ultrasound measures nuchal translucency, and blood tests assess specific markers like PAPP-A and hCG.
