Mass concentration (g/dL or g/L) is the most common measurement unit in the United States.
Enzyme activity (kat) is commonly used for e.g. Reference ranges for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Is usually given with dL (decilitres) as the denominator in the United States, and usually with L (litres) in, for example, Sweden. Reference ranges for blood tests are studied within the field of clinical chemistry, the area of pathology that is generally concerned with analysis of bodily fluids. Molar concentration (mol/L) is used to a higher degree in most of the rest of the world, including the United Kingdom and other parts of Europe and Australia and New Zealand. International units (IU) are based on measured biological activity or effect, or for some substances, a specified equivalent mass. liver function tests like AST, ALT, LD and v-GT in Sweden.
Regardless of the units that the lab uses, your results will be interpreted in relation to the reference ranges supplied by the laboratory. The units of measurement that labs use to report your results can vary from lab to lab. Some lab test parameters such as Calcium (Ca), Sodium (Na), Potassium (K) and others can be measured in mmol/L (or mEq/L) or in mg/dl. He can decide to note your weight in pounds or in kilograms. Usually there is only one record of reference range interval for each test procedure. You can adjust measurement units naming and reference ranges as well. It is similar to the way, for instance, your physician chooses to record your weight during an examination. Your laboratory report may show different units of measurement than we have in Medical Tests Analyzer and the naming can be updated as well. However it can be specified several interval records for different ages and genders. By using the tool you will be able to adjust the reference ranges and units of measurement and store them. The units of measurement along with reference ranges that labs use to report your results can vary from lab to lab. In this same way, labs may choose to use different units of measurement for your test results. Medical Tests Analyzer provides default values of reference ranges and units of measurement for each lab test procedure that produces quantitative results. By using the 'Reference Ranges' interface you are able to update name of measurement units and the parameter's reference range.
DDxHub is a concentrator that holds a lot of disease descriptions. It relies on the System knowledgebase to diagnose a health condition.
