Recommendation of a highly sensitive method for measuring hemoglobin in hemolytic test / 生物医学工程学杂志

In this paper is recommended a highly sensitive and reagent-safe method to determine plasma heamoglobin (FHb) in viscacha hemolytic test. The 2,4-dichlorophenol method (2,4-DCP) of Trinder reaction has been improved. The performance of 2,4-DCP is verified. The sensitivity of 2,4-DCP is 2.39 times that of phenol method. It is well used with run precision and day-to-day precision. The reaction color is stable. The reference value FHb is 1-36.7 mg/L. Sodium citric is an excellent anticoagulant liquid to keep erythrocyte. The 2,4-DCP method is neither carcinogenic nor poisonous;it is suitable for viscacha hemolytic test in clinical and biomedical engineering.
