Pregnancy tests are tools used to determine whether a person is pregnant, primarily by detecting the hormone human chorionic gonadotropin (hCG) in urine or blood. Here's a detailed look at how pregnancy tests work, the different types available, and how to use them:

1. How Pregnancy Tests Work:
- hCG hormone:
When a fertilized egg implants in the uterus, the body starts producing hCG. This hormone can be found in the urine or blood, and levels rise rapidly in the early stages of pregnancy.
- Detection:
Pregnancy tests are designed to detect hCG. The presence of this hormone indicates pregnancy.

2. Types of Pregnancy Tests:
- Urine tests:
These are the most common and can be done at home or at the doctor's office. Home pregnancy tests are widely available at pharmacies.
- Home pregnancy tests:
These tests usually include:
- collecting urine in a cup or directly on a test stick.
- Waiting a certain amount of time (usually a few minutes) to see if a line appears on the test.
- Tests can be digital (showing "pregnant" or "not pregnant") or non-digital (showing lines).

- Blood tests:
These are done in a healthcare provider's office and can detect pregnancy before a urine test.
- Qualitative blood test: This test checks for the presence of hCG. It gives a simple yes or no answer about pregnancy.
