The Association of Practising Pathologists is an association of Pathologists with Postgraduate Qualification running their own establishments. The Association has honour of being a Stakeholder at International Laboratory Accreditation Cooperation (ILAC), Sydney.

The need of this association in addition to Indian Association of Pathologists and Microbiologists was discussed in a meeting of eminent pathologists in June 1999. It was decided that since our requirements and problems are totally different from Service Pathologists we should have an additional Association fulfilling the needs of Practising Pathologist. Ultimately this APP was formed on June 2nd 2001 in a meeting of more than 28 Practising Pathologists from Delhi and NCR.

A constitution was framed and passed in subsequent General Body Meeting. It was subsequently registered under S.R. Act of 1860 (Punjab Amendment Act Of 1952)
The Registered office is situated in the National Capital Territory of Delhi at Eskay Lab C-4/19 Acharya Niketan, Mayur Vihar-I, Delhi 110092.

At present there are more than 150 Life members.

There is no provision of Ordinary members.
