Can lab tests have errors?

FAQ:

Can lab tests have errors?

Answer:

While lab tests are very reliable, no diagnostic test is perfect, and occasional errors and variations can occur.

These may result from biological factors, sample handling, or preparation issues like not fasting or being dehydrated before testing.

If a result is unexpected, it doesn’t necessarily mean it’s an error—it may simply reflect temporary fluctuations in your body or a response to specific conditions at the time of testing.

Why tracking trends matters:

This is why, rather than relying on a  single test as a definitive answer, it’s valuable to track trends over time. Establishing a baseline and testing periodically allows you to better understand your body’s patterns and make informed decisions about your health.
