This is yet another rapidly growing, low investment small business idea in India. It simply means you collect blood, stool, urine and sputum samples from patients, from their homes. These samples are for delivery to pathological labs that will test them and issue medical reports. The reports have to be home delivered to the customer. You will require a vehicle, equipment to store the bio-hazardous material and skills in extracting blood samples. You will need agreements with pathological labs before entering into this business.
