Mumbai, Dec. 30 -- The State Blood Transfusion Council (SBTC) has cautioned blood banks against collecting blood beyond local requirements, particularly during donation drives in December-February. In a directive issued on December 26, the SBTC warned that blood banks found diverting surplus blood components to other states will face strict action, including cancellation of their licences. "Blood collection must be based on the average distribution of the last three years in the city, district and nearby districts," the directive issued by the SBTC said. The council said that while blood donation camps are often organised in December-February to coincide with major festivals, it had found some blood banks deliberately collecting more blood than required, separating the components and transferring excess packed red blood cells and plasma to other states or plasma fractionation companies for profit. "Such misconduct, including bulk transfer of excess blood, will invite strict action, including recommendation for cancellation of licences," the SBTC's directive said. The council said it will monitor blood collection closely in the coming months and coordinate with the FDA to ensure compliance with the directive. Meanwhile, officials from blood banks run by the Brihanmumbai Municipal Corporation (BMC) said government hospitals were suffering due to excess blood collection by private blood banks. "Private blood banks email the SBTC saying they have excess stock. But when government hospitals ask for blood, it is never supplied to us. Instead, it is sold or transferred to other states," a senior civic-run blood bank official at a BMC hospital told Hindustan Times, requesting anonymity. Structural gaps and lack of component separation labs and related infrastructure at government hospitals worsen the problem, the official noted. "The donor pool for both government and private blood banks is the same, and private banks often provide gifts and incentives to donors. Once a person donates (blood), they cannot do so again immediately. So aggressive private drives reduce availability for government hospitals," he said. Another civic blood bank official said high-volume collection in December-February often leads to wastage. "Whole blood has a shelf life of 35 days. December collections expire in January, and fresh drives in January and February add even more stock," the official said. "We have seen emails sent by private blood banks to the SBTC saying they have over 1,000 litres of blood in excess." Officials also flagged concerns around plasma trade, and alleged that private blood banks are incentivised to collect excess blood during these months due to rising demand and pricing for plasma components. Hindustan Times reached out to two private blood bank owners regarding allegations of excess blood collection. One declined to comment on the matter while another denied any wrongdoing....
