WHPM INC,Irwindale

W.H.P.M., Inc., established in 1993, is a privately held corporation headquartered at Irwindale, California, only 15 minutes away from downtown Los Angeles. The Company is a pioneer in the research and development of one-step rapid membrane tests. It has been designated a registered GMP facility for in vitro diagnostic medical devices by the FDA.

W.H.P.M. is established upon over a decade of research in the bio-technological industry. Its scientific professional team has applied these years of R&D experience to their development of one-step membrane immunoassay tests. With the strong support of our sister company, WHPM Bioresearch Technology Co., Ltd., W.H.P.M. has continuously researched, developed, and produced high quality rapid test systems that have not only revolutionized the pharmaceutical industry, but have also set new industry standards and guidelines.

We also develop and manufacture our own anti-bodies based on our in house developed clones. This allows W.H.P. M. Inc. to ensure:

  • Highly stable test results from lot to lot

  • Reliable supply chain to ensure product availability

  • Very competitive pricing from raw materials through to its finished products

W.H.P.M. Inc. manufactures its branded, OEM and private label products in Beijing, China. We are also unique in that we acquired a US manufacturing facility (CareHealth America Corp.) in 2018 and can offer American made products to those clients that require it.

Our current product leader is a trade name recognized worldwide. In year 2001, W.H.P.M. was proudly designated a sponsor in providing high quality immunological fecal occult blood tests for a large colorectal cancer-screening program; over 20,000 people in Beijing, China took part in the study. In April 2004, the Company sponsored another colorectal cancer-screening program in Hangzhou, China, in which over 60,000 people participated. Upon completion, these two recent studies together will surpass any previous clinically related studies in the world in terms of size and scope.

Through continuing clinical development, W.H.P.M. is committed to building a portfolio of quality products. Using only the highest standards, we deliver our products to the marketplace at highly competitive and affordable prices.
