Companion diagnostics is an emerging diagnostic test used in a drug to ascertain its effectiveness
The companion diagnostics is an important diagnostic test utilized in a drug to ascertain its effectiveness to a particular individual suffering from debilitating illnesses like cancer, AIDS, and HIV to mention only a few. The test assists physicians in determining whether a particular drug is suitable for the individual or not and also helps them in prescribing a proper dosage of a drug to the patient. The results of the test are given in an instant by a trained physician attached to a clinic or hospital so that the individual can make informed decisions regarding his drug therapy. The results are highly valuable to physicians as they are able to interpret them in accordance with their existing knowledge and experience.
One such drug development process that uses the application of Companion Diagnostics in conjunction with biochemistry assays is the Human UTI Clinical trial which aims to identify the usefulness of a specific antibiotic in the treatment of patients suffering from Urinary tract infections. The test is undertaken using urine samples from healthy volunteers, which are then analyzed under the guidance of a specially trained urinalysis expert. This analysis helps the doctor to evaluate the presence and absence of bacteria present in the urine sample and suggest the possible usage of the antibiotic.
The data provided by the test helps the physician to determine the drug course of action and suggest the right dosage that needs to be given to the patient. This also helps in reducing the occurrence of further complications in the long run. Other applications of Companion Diagnostics in the field of drug development include the predictive maintenance therapy for high blood pressure and heart problems and also the development of new allergy screening tools for the management of asthma and other allergic conditions.
