What is Hen's egg test on chorioallantoic membrane?
The '''Hen's egg test on chorioallantoic membrane''', or '''hen's egg test''' is a test that can be used to test the [[toxicity]] of substances. It is also often used to test [[Vaccine|vaccines]]. It is a [[CAM Assay]]. The product to be tested is applied to a special [[membrane]]. Such tests were first used because chicken eggs were easily available. As the respective membrane does not contain any [[nerve cells]], it is likely that the developing bird [[embryo]] does not feel pain during the test. These tests are not considered to be [[animal testing]]. This test can be used as a replacement for the [[Draize test]], as it similarly detects irritation response in cosmetics. <ref>{{cite journal |last1=Husain |first1=Asif |title=A Review on Alternative Methods to Experimental Animals in Biological Testing: Recent Advancement and Current Strategies |journal=Journal of Pharmacy & Bioallied Sciences |date=December 11, 2023 |volume=15 |doi=10.4103/jpbs.jpbs_380_23 |url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10790740/ |accessdate=March 11, 2024}}</ref> ==References== {{Reflist}} {{stub}} [[Category:Animal rights]] [[Category:Toxicology]]
