In Singapore, the Purity Test refers to a comprehensive examination conducted by the Health Sciences Authority (HSA) to determine the purity and quality of pharmaceutical products. The HSA is the regulatory body responsible for regulating health products, including medicines, in Singapore.

The Purity Test aims to ensure that the pharmaceutical products available in Singapore meet stringent quality standards and are safe for consumption. It involves analyzing samples of the products to assess their chemical composition, purity, and presence of any impurities or contaminants.

The specific materials and methods used in the Purity Test may vary depending on the type of pharmaceutical product being tested. The HSA employs advanced laboratory techniques and equipment to conduct the tests, including chromatography, spectroscopy, and mass spectrometry, among others.
