About the Section

Pharmaceutical Samples
Pharmaceutical samples

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 Pharmacy and Poisons Ordinance
  • The Antibiotics Ordinance
  • The Water Pollution Control Ordinance, and
  • The Public Health (Animals and Birds) Ordinance

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 2016
(Actual)
2017
(Actual)
2018
(Plan)
Urgent samples relating to pharmaceutical incidents within two working days (%) 95 100 100 95
Other pharmaceutical samples within reporting time averaging 25 working days (%) 95 97 99 95

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

Key Indicators

Key Indicators for Statutory Testing of Pharmaceuticals

Tests Performed on Pharmaceuticals 2016
(Actual)
2017
(Actual)
2018
(Estimate)
Urgent samples relating to pharmaceutical incidents 655 725 N.A.
Other pharmaceutical samples 54,087 54,598 51,000

As the testing requirements for urgent samples relating to food, pharmaceuticals and Chinese medicine incidents fluctuated in previous years, it is difficult to estimate either the occurrence of these type of incidents or the number of tests required.
