To assess the effectiveness of novel medicines and gauge the severity of the deadly disease cystic fibrosis, researchers have created a test that's urine that measures it. A newly-developed urine test can make it much easier for doctors to diagnose how badly a patient is affected by the hereditary disease cystic fibrosis, which amongst other things alters the body's respiratory, digestive and reproductive systems. The test can also reveal the extent to which the patient's medical treatment is of benefit. This has been shown by a new study from Aarhus University and Aarhus University Hospital that has just been published in the scientific journal Annals of Internal Medicine.
