Is My PSA Level Normal? The absolute value of PSA has been the long-term standard of care to determine whether one’s PSA elevation is significant. Previously, the magic number of “4” was defined as being the upper limit of “normal.” However, this may not be a good rule of thumb since approximately 15% of prostate cancers can occur in men with a “normal” PSA. When interpreting a PSA value, several factors need to be taken into consideration—not just the absolute value of the PSA. Some of these factors include: Age adjustment of the PSA PSA density Percent free PSA PSA velocity Age-Adjusted PSA Recent data has redefined the way that urologists look at PSA, and what is considered a "normal" PSA. Age-adjusted PSA values take into account that a 40-year-old should not have the same PSA as an 80-year-old. Accepted age-adjusted PSA rates are below 2.4 ng/ml for men under...
Alternative Names Serum angiotensin-converting enzyme; SACE Normal Values Normal values vary based on your age and the test method used. Typically, adults have ACE levels less than 40 micrograms/L. 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 ACE levels may be a sign of sarcoidosis. However, increased ACE levels may also be seen in several other disorders, including: Active histoplasmosis Amyloidosis Asbestosis Berylliosis Diabetes Emphysema Gaucher's disease Hepatitis Hodgkin's disease Hyperthyroidism Idiopathic pulmonary fibrosis Leprosy Lung cancer Nephrotic syndrome Primary biliary cirrhosis Pulmonary embolism Scleroderma Silicosis Tuberculosis A decrease in ACE levels may indicate: Steroid therapy (usually prednisone) Therapy for sarcoidosis
