Boluoke® is the only lumbrokinase that has been thoroughly researched and its enzymatic strength is standardized. Other lumbrokinase products currently on the market often are citing Boluoke®’s credentials and research, and are not disclosing the enzymatic strength of their lumbrokinase. On the raw material market, the price of lumbrokinase can vary by up to 15 folds, and the enzymatic strengths of various lumbrokinase also differ greatly. In addition, lumbrokinase is a preparation containing multiple enzyme fractions, and the extraction and purification methods would determine the final compositions of the various enzyme fractions. Therefore, different products would have different lumbrokinase compositions and cannot be considered the same. This is also the reason why Boluoke® does not significantly affect blood tests like prothrombin time (PT) or activated partial thromboplastin time (aPTT), while other lumbrokinase products may affect the test results.
