One of the major pitfalls that may arise in animal study is the delay in testing and the time the specimen is received from the supplier. Due to the demand for animals for many pre-clinical trials, it is important to have multiple animal suppliers. Also, outsourcing an animal study 1000 miles away involves transportation cost. One must allocate the shipping and receiving time of the animals. It is not always wise to outsource the animal study because there are lot of connections working there. One must factor in the cost of the study, shipping and receiving cost and the lead time prior to making the final decision. Also, expand the testing to be done on multiple animals so that there is an alternate option to finish the tests.
