The blood seized by the police with fake labels of the state's largest blood bank at King George's Medical College (KGMC) were sent for detailed examination to the SGPGIMS.

While SGPGIMS officials were tight-lipped about their findings, it is learnt that the tests revealed large scale adulteration of blood with saline water. 'Mixing saline water leads to further dilution of the already low haemoglobin blood,' said a senior KGMC pathologist.

Lucknow's Superintendent of Police (City) Paresh Pandey, who was responsible for busting the racket, had initially said he suspected animal blood was being mixed with human blood. Later, it was realised that the blood was being diluted with saline water.
