Over the years, Dr. Meo earned several international certifications, including registration as a Medical Laboratory Technologist in Canada. He also trained in Chinese alternative medicine and became one of the first healthcare professionals in Pakistan to promote integrative health methods. In 2005, he introduced Quantum Health Analyzer technology to Pakistan after researching its benefits for diagnosing chronic and neurological conditions. His early use of this technology brought relief to many patients and opened new paths in preventive care.

Dr. Zahid Meo has worked with respected institutions such as Social Security Hospital, Landhi, Dow Medical College, and Civil Hospital Karachi. He played a major role in the development of blood banking services in Pakistan. He was a founding member of the Fatimid Blood Bank, which became a lifeline for patients with conditions like thalassemia and cancer. With government support during General Zia-ul-Haq’s era, Fatimid became one of the first centers in Pakistan to develop blood products. Later, Dr. Meo also established Saba Blood Bank, which expanded to four branches in Karachi and served thousands before closing in 2000 due to financial challenges.
