Hemolysis Evaluation

Hemolysis is a very serious manifestation of drug toxicity. Our company has extensive expertise in local toxicity evaluation, particularly in hemolysis evaluation. We employ talented and highly trained scientists who focus on every aspect of rare disease therapy research and development and have the capabilities and resources to provide a one-stop and customized hemolysis evaluation service.

Overview of Hemolysis Evaluation

Hemolysis refers to reactions such as hemolysis and red blood cell aggregation caused by drug preparations. Hemolysis occurs by two mechanisms, namely toxic hemolysis and allergic hemolysis. All injections and other topical pharmaceutical preparations that may cause immune hemolysis or non-immune hemolysis should undergo hemolysis evaluation. The purpose of drug hemolysis evaluation is to determine the impact of drugs or related preparations on the activities of red blood cells, the complement system, coagulation factors, and various enzymes in the blood by observing whether hemolysis occurs and its extent.

Types of Hemolysis

Intravascular Hemolysis

Intravascular hemolysis occurs within blood vessels and involves the direct destruction of red blood cells.

Extravascular Hemolysis

Extravascular hemolysis occurs outside blood vessels mainly in the spleen and liver.

Immune-Mediated Hemolysis

Immune-mediated hemolysis occurs when red blood cells are targeted and destroyed by the immune system.

Our Services

With the world-leading preclinical rare disease research platform, our company provides professional hemolysis evaluation services. Our team will customize the experimental design for your project according to your specific requirements.

We use in vitro test tube method to evaluate the hemolysis of drugs, comparative studies with marketed preparations of the same route of administration, and in vivo tests in animals or combined with repeated drug toxicity tests. The related indexes of hemolytic reaction (reticulocyte, red blood cell count, bilirubin, urine protein, changes of kidney, spleen, and liver, etc.) were observed.
