Thai Authorities Clarify Health Data Accuracy on 'Tang Rat' App

On July 31, 2026, the Big Data Institute (BDI), the Digital Government Development Agency (DGA), and the National Health Security Office (NHSO) issued a joint clarification regarding the 'Tang Rat' application. This response follows public concerns regarding 'KeyTip,' where users reported that health information displayed on the app appeared to be incorrect or falsified.

According to the authorities, the 'Tang Rat' application and the 'Health Link' system function strictly as display interfaces. These platforms aggregate and present health data transmitted from original medical service providers. The agencies emphasized that the systems do not possess the capability to edit, alter, or modify the medical records provided by the source institutions. The discrepancies reported by users are attributed to the initial data entry processes performed by the respective public health units where the examinations or treatments occurred.

For residents and travelers using the 'Tang Rat' app to access their digital health records, this clarification confirms that the app is a mirror of existing hospital databases rather than a primary record-keeping system. If you encounter incorrect medical information, the data must be corrected at the source—the specific hospital or clinic where the service was provided. It remains to be confirmed how the Ministry of Public Health will streamline the process for patients to request corrections from these individual service providers to ensure future data integrity.
