Key Functions of Phlebotomy in Medical Practice
- Diagnostic Testing: Blood analysis aids in diagnosing various health issues.
- Monitoring Disease Progress: Regular blood draws monitor how well treatments are working.
- Blood Donation: Contributing to blood banks to support care for patients in need.
