Important Considerations:

* Individual Variability: Ranges may vary based on factors like age, sex, and overall health.
* Lab-Specific Ranges: Different laboratories may have slightly different reference ranges due to testing variations.
* Healthcare Provider Consultation: Always consult a healthcare provider for accurate interpretation and personalized advice based on your results.

By understanding these general reference ranges, you can gain a preliminary understanding of your test results. However, it is essential to discuss these results with your healthcare provider for proper interpretation and appropriate medical guidance.
