Merck always focuses its efforts on public health where Merck can utilize its expertise to help improve the quality of public health. For screening and diagnosing the risk of thyroid disease, the TSH test is a very important process to find out whether someone is suffering from thyroid disease or not. In this case Merck voluntarily makes donations to non-profit health organizations to provide free TSH tests to the general public or patients. Merck believes that donating TSH tests for patients through PB IDI is a worthy effort and reflects Merck's commitment to society without intending to receive any form of compensation for the donation.
