(Newser) – The FDA has found a contaminant in samples of heparin, a blood thinner produced mainly in China linked to 19 deaths and nearly 800 allergic reactions in the US, the New York Times reports. The contaminant may be a counterfeit form of heparin added to reduce its manufacturing cost. The FDA is fine-tuning tests to better detect it.

“At this point, we do not know whether the introduction was accidental or whether it was deliberate,” said an FDA official. Neither do they know whether the contaminant was introduced in China, where the raw components of heparin are produced, or in US processing facilities. While the FDA has yet to prove the contaminant caused the deaths, it was found only in samples associated with illnesses. (Read more Heparin stories.)
