It is well known fact that Americans love caffeine. In fact, it is estimated that approximately 80% of American adults take a certain dose of caffeine every day. Now, new research has found that the consumption of caffeine is so large that it was detected 100% of purely analyzed blood samples that were provided by blood banks. These blood samples are usually used for transfusions in hospitals across the US. In addition, traces of alprazolam were also found in a large number of blood bank samples that were analyzed. The latter being called the anxiolytic prescription drug Xanax and cough medicine.
The two scientists of Oregon State University, Luying Chen and Richard van Breemen, purchased 18 samples of pure human blood serum from different biomedical suppliers. These health care providers primarily took blood from blood banks and passed it to health care facilities. Incredibly, all 18 blood samples confirmed positive for caffeine. In the 18 samples, eight were found positive for dextromethorphan and 13 showed traces of Xanax. In addition to what these effects results could mean for many patients with blood transfusions, the authors of the study said that their findings indicated that large amounts of blood used for research purposes are contaminated.
From a ‘contamination’ perspective, caffeine is not a big deal for patients. Although it may be a comment on today’s society, according Mr. Chen, a Ph.D. student. But the other drugs present there can cause problems for patients and also for researchers because it is difficult to obtain clean blood samples. Additionally, the blood samples were tested for tolbutamide, which is a drug used for the treatment of type 2 diabetes, but no traces were found. Although the results indicated that millions of blood transfusion patients are receiving additional caffeine, cough medicine, or Xanax. The study authors of the study warned that their sample size were relatively small. According to Mr. Breemen, the director of Linus Pauling Institute of Oregon State University, the study led in the direction to speculate that how widespread is the problem.
