Metrication of clinical laboratory data in SI units. 1976

H P Lehmann

The development and general concepts of the Système International d'Unités (SI units) are discussed. The basic and derived quantities and units of the SI used for clinical laboratory data are reviewed. Ranges of normal values for a number of body fluid constituents are given in the units in current general use and in SI units, with corresponding conversion factors.

D007753	Laboratories	Facilities equipped to carry out investigative procedures.	Laboratory
D008792	Metric System	A system of units used in scientific work throughout the world and employed in general commercial transactions and engineering applications. Its units of length, time, and mass are the meter, second, and kilogram respectively, or decimal multiples and submultiples thereof.

D008829	Microbiology	The study of microorganisms such as fungi, bacteria, algae, archaea, and viruses.
D008853	Microscopy	The use of instrumentation and techniques for visualizing material and details that cannot be seen by the unaided eye. It is usually done by enlarging images, transmitted by light or electron beams, with optical or magnetic lenses that magnify the entire image field. With scanning microscopy, images are generated by collecting output from the specimen in a point-by-point fashion, on a magnified scale, as it is scanned by a narrow beam of light or electrons, a laser, a conductive probe, or a topographical probe.
