A laboratory infrastructure has been created through a partnership with a private laboratory in India, Dr Lal PathLabs (https://www.lalpathlabs.com/), which has a network of sample collection centres, regional laboratories and a national reference laboratory in New Delhi, India. Their existing service delivery model was adapted to the requirements of the MaatHRI platform. All biological samples are analysed at the National Reference Laboratory. The precision, performance and quality of each laboratory parameter are documented and maintained to a high level. All MaatHRI research nurses have been trained by experts from Dr Lal PathLabs to collect, centrifuge and pack samples. Centrifuge machines of same make and model have been provided to all MaatHRI collaborating hospitals. The laboratory provides the required blood collection kits with specific written guidance to all study hospitals for collecting, processing and packing the blood samples.
