Or is it? Abstract & Commentary. In the Cardiovascular Health Study, which included subjects ≥65 years old, isolated TSH elevations between 4.5 and 20 mU/L were not associated with increased coronary heart disease (CHD), cerebrovascular disease, cardiovascular risk, or all-cause mortality over 13 years of follow-up, and only patients with TSH levels ≥10 mU/L were more likely to progress to overt hypothyroidism (22, 23, 39). Should I be concerned? " Answered by Dr. Donald Colantino: No concern: Both bun and creatinine are unremarkable in my opinion. BUN and High-Dose Loop Diuretics. Here's how your body typically forms and gets rid of urea nitrogen: Interaction between loop diuretic-associated mortality and blood urea nitrogen concentration in chronic heart failure.J Am Coll Cardiol 2011;58:375-382. The BUN test is primarily used, along with the creatinine test, to evaluate kidney function in a wide range of circumstances, to help diagnose kidney disease, and to monitor people with kidney dysfunction or failure.It also may be used to evaluate your general health status when ordered as part of a renal panel, basic metabolic panel or comprehensive metabolic panel. You need to see liver specialist ( Hepatologist) and have more testing. Source: Testani JM, et al. By Michael H. Crawford, MD, Editor. #### Learning points If alkaline phosphatase is raised in an asymptomatic patient and serum bilirubin, liver transaminases, creatinine, adjusted calcium, thyroid function, and blood count are normal: A 51 year old asymptomatic … There is isolated ST elevation in aVR and inferolateral ST depression. "Slightly elevated BUN (21), normal creatinine (0.79), elevated Bun/Creat ratio (27). A BUN test measures the amount of urea nitrogen that's in your blood. Elevated AST and ALT are mild. High-dose loop diuretics are often necessary to reduce elevated filling pressures in patients with heart failure. Doctors give trusted, helpful answers on causes, diagnosis, symptoms, treatment, and more: Dr. Friedlander on isolated ggt elevation: Elevated Bilirubin is concerning. That’s a STEMI! This is what the 2013 ACC/AHA STEMI guidelines say about it: “multi-lead ST depression with coexistent ST elevation in lead aVR has been described in patients with left main or proximal left anterior descending artery occlusion”. For example, the acutely ill jaundiced patient with a history of prolonged alcohol ingestion requires a different laboratory assessment than the well patient in whom one or more standard liver test results are discovered to be abnormal during routine testing. Laboratory assessment of the patient with suspected or clinically obvious liver disease is context dependent.

A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys and liver are working. This article discusses the most common causes of raised alkaline phosphatase levels in an asymptomatic patient and provides advice on the relevant investigations.
