TANKER (Tamilnadu kidney Research Foundation)
I came to know from my friend that there is a non-profit social welfare organization that is functioning from Chennai which is called TANKER (TAmil Nadu KidnEy Research Foundation). They help poor patients affected by renal problems free of charge. They also offer free dialysis for poor patients.
You can check out more website about TANKER from their website here and spread the word to your friends so that more people would get benefitted.
