Classification of Clinical Laboratories by Institution

The 2003 amendment revised Section 5.2 for a more precise classification reflecting prevailing operational settings.
The categories were redefined as:
- Institution-based laboratories: Laboratories operating within the premises of and as part of an institution. Examples include hospitals, multi-specialty clinics, educational institutions, medical facilities for overseas workers, and seafarers.
- Freestanding laboratories: Laboratories operating outside any institutional premises and functioning independently.

The amendment applies solely to the classification scheme based on institutional character.
All other rules and regulations under Administrative Order No. 59, s. 2001 remain unchanged and effective.

This amendment was officially adopted on May 23, 2003, by the Secretary of Health, ensuring the updated classification is recognized and implemented in the governance of clinical laboratories in the Philippines.

Clarifies and expands the institutional setting as a basis for classification.
Differentiates between integrated institution-operated laboratories and independently operated laboratories.
Supports regulatory clarity and standardization in clinical laboratory operations.

While not specifically mentioned in the amendment, enforcement and penalties continue to be governed by the existing provisions of Administrative Order No. 59, s. 2001.
