When a healthcare provider orders a lab test, they usually include a note about the reference range. This is the range that is considered normal for that particular test. For example, a normal hemoglobin level is typically between 12 and 15 grams per deciliter (g/dL). reference range can vary depending on the lab that performs the test, so it’s important to ask your provider which range is being used.
Reference ranges are important because they help healthcare providers interpret lab results. They can also be helpful in identifying abnormal results that may require further testing or treatment.
It’s important to keep in mind that reference ranges are just a guide. They may not be accurate for everyone, and they can change over time. If you have any questions about your lab results, be sure to ask your healthcare provider.
