In healthy men and women, urine does not contain any blood that can be seen with the eye, called "gross blood," nor does it contain red blood cells that can be discovered with the aid of a microscope. The discovery of either gross or microscopic blood in urine is a sure indication of the need to examine and evaluate the patient to discover the cause of this abnormality. The conditions that can lead to either gross or microscopic blood in the urine are many and varied. In adults, a careful history to describe the details of the bloody urine, a physical examination and laboratory studies are the first step in unearthing the cause. Imaging with x-rays, ultrasound, CAT/MRI scans are the next step and will usually discover the cause. In adult women, infection of the bladder or kidneys, urinary stones, and tumors of the urinary bladder, kidneys are the most common causes. In adult men, enlargement and/or infection of the prostate, bladder infection and...
Think you can’t donate your tissue since you have rheumatoid arthritis? Think again. Researchers want your tissue and blood samples in order to conduct a variety of research projects.
The Robert S. Boas Center for Genomics & Human Genetics , as part of the Feinstein Institute for Medical Research in New York, is examining patterns in the human genome to find specific genetic risks for diseases such as rheumatoid arthritis or lupus to Alzheimer’s disease and schizophrenia.
Established in 1997 by a group of rheumatologists and researchers from across the country, the North American Rheumatoid Arthritis Consortium (NARAC) has identified several major risk genes for RA . NARAC is led by Feinstein Institute researcher, Peter K. Gregersen, MD, who identified the two polymorphisms associated with RA and lupus - PTPN22 and STAT4 - years ago.
Although there is still much to know about genetic risk factors rheumatoid arthritis and other diseases, co...
Normal Values Normal values range from 2 - 18 units per 24 hours. Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results. What abnormal results mean Increased levels of leucine aminopeptidase can be seen in several conditions: Cholestasis Cirrhosis Hepatitis Liver cancer Liver ischemia (reduced blood flow to the liver) Liver necrosis (death of live tissue) Liver tumor Pregnancy (late stage)
