Why Laboratory Monitoring Matters: Understanding the Purpose of Follow-Up Labs
Many people worry that laboratory testing creates unnecessary barriers to care.
A common question is:
"If I feel fine, why are labs needed?"
The purpose of monitoring is generally not to create obstacles. Instead, laboratory information may help providers understand trends and make informed treatment decisions.
Clinical guidance recommends monitoring appropriate health information throughout treatment as part of individualized care planning.
