Single-dose Toxicity Evaluation

Single-dose toxicity evaluation is used to understand the toxic reactions and severity of animals after administration. Our company has extensive expertise in general toxicology evaluation, particularly in single-dose toxicity evaluation, our professional technical team and comprehensive service platform can provide efficient methods to accelerate your development of rare disease therapy.

Introduction to Single-dose Toxicity Evaluation

Single-dose toxicity evaluation is used to describe the relationship between dose and systemic and/or local toxicity. The purpose is to determine the potential acute adverse effects of the test compound and also to help researchers determine the dose for repeated-dose toxicity evaluation. Single-dose toxicity evaluation can determine the maximum tolerated dose (MTD) and identify potential target organs affected by the compound. In this type of study, the safety of a new drug candidate is typically tested in rodent and non-rodent models, with test animals given a single dose of the compound and all animals monitored for toxicity for 14 days.

Our Services

With extensive experience, our company's toxicologists can select appropriate dose levels for your toxicity studies and design the best experimental protocol. We can provide a complete range of animal species to support in vivo evaluation of single-dose toxicity. At the same time, we have highly sensitive and high-precision analysis methods including HPLC, LC/MS, etc., which can fully meet your scientific research needs.     

  • In Vivo Toxicity Evaluation

Single-dose toxicity studies are performed in animals according to the experimental protocol. The dosage is enough to monitor the toxicity of all animals for 14 days and provide feedback to customers on the progress of the experiment at any time.

  • Mice
  • Rats
  • Rabbits
  • Non-human primates
  • Others

Routes of Administration
