Government Laboratory - Pharmaceutical Chemistry Section

Government Laboratory

Analytical and Advisory Services Division

Pharmaceutical Chemistry Section

About the Section

This Section examines pharmaceutical items for compliance with national pharmacopoeial standards, such as the British Pharmacopoeia and the United States Pharmacopoeia. Majority of the tests carried out are chemical testing. Starting from April 2002, the newly established Microbiological Unit of the Section provides centralized microbiology testing services to the Laboratory.

Responsibilities

This Section conducts analyses for enforcement of the following Ordinances:

The Import and Export Ordinance
The Pharmacy and Poisons Ordinance
The Antibiotics Ordinance
The Water Pollution Control Ordinance, and
The Public Health (Animals and Birds) Ordinance
The Trade Descriptions Ordinanace

In addition, the Section inspects pharmaceutical products, which are prepared by the Pharmaceutical Manufactory of the Department of Health or purchased by the Government Logistics Department and the Hospital Authority, to check on the compliance with specifications.

Targets and Key Indicators

Key Performance Measures Relating to the Statutory Testing of Pharmaceuticals

Targets

Testing of Pharmaceuticals	Targets	2009 (Actual)	2010 (Actual)	2011 (Plan)
Pharmaceuticals (quality control) within reporting time averaging 14 working days (%)^*	95	97	99	95
Pharmaceuticals (registration) within reporting time averaging 30 working days (%)^*	90	94	93	90

Different samples require different analytical procedures, thus different reporting time applies. The quoted number of working days required represents an average of reporting time for the different types of samples / test requests within the category, while the target (in percentage) is the total compliance rate of the concerned samples / test requests within a particular category against their respective targets.
