About the Section

Chinese medicine samples
Chinese medicine samples

This Section was established on 7th October 1998. Its major responsibilities are to carry out safety monitoring of proprietary Chinese medicines and Chinese herbal medicines on sale to the public and to conduct development work on analytical methodology.

 

 

 

 

 

 


Responsibilities

This Section examines Proprietary Chinese medicines and Chinese herbal medicines submitted mainly by the Department of Health.

Proprietary Chinese medicines and Chinese herbal medicines are analyzed for their safety and quality including the determination of pesticide residues and heavy metals/toxic element. Urgent analytical services are also provided to DH in relation to investigation into the causes of poisoning cases and reports of adverse drug reactions involving the consumption of Chinese medicines. Proprietary Chinese medicines are tested for the presence of chemical markers for the certification of suspected unregistered products.

Targets and Key Indicators

Key Performance Measures Relating to the Statutory Testing of Chinese Medicines

Targets #

Testing of Chinese Medicines Targets 2017
(Actual)
2018
(Actual)
2019
(Plan)
Urgent samples relating to Chinese medicine incidents within two working days (%) 95 100 100 95
Other Chinese medicine samples within reporting time averaging 30 working days (%) 95 99 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.

(Estimate)
Urgent samples relating to Chinese medicine incidents 584 276 N.A.§
Other Chinese medicine samples 83,828 81,084 80,000

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