Pregnancy Test (hCG)

What is being analysed?

The Pregnancy Test, specifically focusing on the human chorionic gonadotropin (hCG) hormone, is a diagnostic tool used to determine pregnancy. This hormone is produced by the placenta after a fertilised egg attaches to the uterine lining. 

How is it used?

The test is commonly performed using urine or blood samples. It detects the presence and quantity of hCG, providing crucial information about pregnancy status.

 

Why undergo the analysis?

The primary purpose of the Pregnancy Test is to confirm or rule out pregnancy. Early detection can guide timely medical care and decision-making.

 

When to undergo the analysis?

The test is typically performed a few days after a missed period, as hCG levels rise rapidly during early pregnancy. However, it can be done at any time if pregnancy is suspected.  

 

What sample is required?

Both urine and blood samples can be used for the test. Home pregnancy tests usually involve urine samples, while healthcare professionals may prefer blood tests for increased accuracy.

 

Is any type of prior preparation necessary?

No specific preparation is required. However, for blood tests, it is advisable to inform the healthcare provider about any medications or supplements being taken.

 

How is it used?

For urine tests, a woman typically collects a sample in a container or uses a home pregnancy test kit. Blood tests are conducted in a healthcare setting, where a small blood sample is drawn for analysis.
