Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
another version of the BRAT diet: bananas, rice, applesauce, toast, yogurt (helps digestion in some GI disorders) BRB: bright red blood (color is important as an indicator of source, for example in gastrointestinal bleeding) BRBPR: bright red blood per rectum: BRCA1 (gene) BRCA1 (protein) breast cancer 1 (a human gene and its protein) BRCA2 (gene)
Blood tests are also used to assess kidney function. These include tests that are intended to directly measure the function of the kidneys, as well as tests that assess the function of the kidneys by looking for evidence of problems associated with abnormal function. One of the measures of kidney function is the glomerular filtration rate (GFR).
A medical test is a medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, or to determine a course of treatment. Medical tests such as, physical and visual exams, diagnostic imaging, genetic testing, chemical and cellular analysis, relating to clinical chemistry and molecular diagnostics, are typically performed in a medical setting.
Outside the United States, blood tests made up of the majority of the same biochemical tests are called urea and electrolytes (U&E or "U and Es"), or urea, electrolytes, creatinine (UEC or EUC or CUE), and are often referred to as 'kidney function tests' as they also include a calculated estimated glomerular filtration rate. The BMP provides ...
In medicine and medical statistics, the gold standard, criterion standard, [1] or reference standard [2] is the diagnostic test or benchmark that is the best available under reasonable conditions. [3] It is the test against which new tests are compared to gauge their validity, and it is used to evaluate the efficacy of treatments. [1]
Diagnostic tests are undertaken to determine whether a patient has a disease assured or undifferentiated of the connective tissues. [ 10 ] Patients with UCTD usually have positive ANA (antinuclear antibody), and raised ESR ( erythrocyte sedimentation rate) values, without typical autoantibody specificities. [ 14 ]
