The presence of hCG (human chorionic gonadotropin) in urine isn't visually detectable with the naked eye. It doesn't change the color or appearance of the urine itself. Instead, home pregnancy tests contain reactive paper that detects hCG, and the test displays a result based on whether hCG is present above a certain threshold.
Here's what you should look for on a home pregnancy test:
-
The Actual Urine: The urine itself will appear normal. You are looking for the test result, not a change in the urine's physical appearance.
-
Positive Test Indicators: A positive pregnancy test indicates that hCG has been detected. The way this is displayed varies by test brand. Common indicators include:
- A plus sign (+): One line usually appears to show the test is working. A second line forming a plus indicates a positive result.
- Two vertical lines (||): Similar to the plus sign, one line is a control, and the second indicates a positive result.
- The word "Pregnant": Some digital tests directly display the word "pregnant" if hCG is detected.
-
Negative Test Indicators: The test will show a negative result if hCG is not detected or is below the threshold for the test. Common indicators include:
- One vertical line (|): This usually indicates that the test worked correctly but no hCG was detected.
- A minus sign (-): One line typically appears, meaning the test is valid and negative.
- The word "Not Pregnant": Some digital tests directly display the words "Not Pregnant"
Important Notes:
- Read the Instructions: Always carefully read and follow the instructions included with your specific pregnancy test. Different tests may have slightly different appearances or interpretations.
- Faint Lines: A faint line may indicate a low level of hCG, potentially due to early pregnancy. Retest in a few days, or consult a doctor to confirm.
- False Negatives: Testing too early in pregnancy can result in a false negative.
- Confirmation: Home pregnancy tests are generally reliable, but it's always best to confirm the result with your doctor through a blood test.
