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 ...
Using magnetic nanoparticles studded with a beta-2-glycoprotein I peptide imitating a plasma protein, microbial pathogens could selectively be retrieved from blood culture specimens within hours, in a study published September 2024. Magnets are used to fish out the peptide-bacterial complex, followed by genetic testing.
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.
In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of ...
The differential diagnosis of normal anion gap acidosis is relatively short (when compared to the differential diagnosis of acidosis): Hyperalimentation (e.g. from TPN containing ammonium chloride) Chloride administration, often from normal saline; Acetazolamide and other carbonic anhydrase inhibitors; Renal tubular acidosis [1]
A portolan nautical chart of the Mediterranean Sea, second quarter of the 14th century. Kept in the Library of Congress, where it is the oldest original cartographic artifact. Portolan charts are nautical charts, first made in the 13th century in the Mediterranean basin and later expanded to include
It normally ranges from 1.003 to 1.035; lower values indicate that the urine is dilute, while higher values mean that it is concentrated. A urine specific gravity that consistently remains around 1.010 ( isosthenuria ) can indicate kidney damage, as it suggests that the kidneys have lost the ability to control urine concentration.

The p-chart only accommodates "pass"/"fail"-type inspection as determined by one or more go-no go gauges or tests, effectively applying the specifications to the data before they are plotted on the chart. Other types of control charts display the magnitude of the quality characteristic under study, making troubleshooting possible directly from ...
