The RML Mehrotra Pathology was started in 1954 at Lucknow the capital of Uttar Pradesh by Prof. R.M.L.Mehrotra eminent pathologist of the country.  At that time very few private pathology Labs existed in the country and the science was in very basic stage of its development.   Very few basic tests were available for the diagnostic help of the patients.  The technology was not well developed at the time.  The pathologists were known by their microscope and many of the diagnosis were based on the expert use of these gadgets.

Prof.R.M.L.Mehrotra was a visionary and knew that in coming time this science would evolve and shall become the back bone of the all clinical sciences in achieving the diagnosis and monitoring the patients.

Over period of time RML Lab has become one of the big Labs in clinical pathology services. The Lab is quick to adapt to the developing technologies and its application for the use in clinical medicine.

Since then the lab has been no looking back, and has expanded immensely to provide a wide range of tests possible today in the field.
