AU/ml Unit of measure of potency of allergenic product expressed as a number of allergy units per one milliliter of formulation.
DK units/ml The NIDDK calibrators were tested together with dilutions of the WHO reference serum using harmonized assays on five occasions in the BDC, Bristol, and Munich laboratories and reported as WHO units/ml by calibration as previously described. For each of the NIDDK calibrators, the median value of the WHO units/ml obtained for the 15 measurements was assigned as its calibrator unit. The assigned units were termed digestive and kidney units (DK units)/ml.
g/dl A unit of mass concentration defined as the concentration of one gram of a substance per unit volume of the mixture equal to one deciliter (100 milliliters). The concept also refers to the metric unit of mass density (volumic mass) defined as the density of substance which mass equal to one gram occupies the volume one deciliter.
g/l grams per liter
HAU hemagglutination units
iu/l Unit of arbitrary substance concentration (biologic activity concentration) defined as the concentration of one international unit per one liter of the system volume.
IU/ml A unit of arbitrary substance concentration (biologic activity concentration) defined as the concentration of one international unit per one milliliter of system volume.
Kallikrein Inactivator Unit per Milliliter An arbitrary unit of a kallikrein inactivator concentration equal to the concentration at which one milliliter of the mixture contains one unit of the kallikrein inactivator.
M molar
mg/dl A unit of mass concentration defined as the concentration of one milligram of a substance in unit volume of the mixture equal to one cubic deciliter or 100 cubic centimeters. It is also a unit of mass density (volumic mass) defined as the density of substance which mass equal to one milligram occupies the volume one cubic deciliter or 100 cubic centimeters.
mg/l A metric unit of mass concentration defined as the concentration of one gram of a substance per unit volume of the mixture equal to one cubic meter. The concept also refers to the metric unit of mass density (volumic mass) defined as the density of a substance which mass equal to one gram occupies the volume of one cubic meter.
mg/ml microgram per milliliter
miu/ml Unit of arbitrary substance concentration (biologic activity concentration) defined as the concentration of one international unit per one liter of the system volume.
mM millimolar
MOI multiplicity of infection
ng/dl A unit of mass concentration defined as the concentration of one nanogram of a substance per unit volume of the mixture equal to one deciliter. The concept also refers to the unit of mass density (volumic mass) defined as the density of substance which mass equal to one nanogram occupies the volume of one deciliter.
ng/ml nanogram per milliliter
ng/nl nanogram per nanoliter
ng/ul nanogram per microliter
nM nanomolar

NPX NPX, Normalized Protein eXpression, is Olink's arbitrary unit which is in Log2 scale. It is calculated from Ct values and data pre-processing (normalization) is performed to minimize both intra- and inter-assay variation. NPX data allows users to identify changes for individual protein levels across their sample set, and then use this data to establish protein signatures. The NPX scale is inverted compared to that of Ct. This means that a high NPX value equals a high protein concentration. Because NPX is in a log2 scale, a 1 NPX difference means a doubling of protein concentration. If needed NPX values can be converted into linear scale: 2^NPX= linear NPX.
optical density The measurement of the light transmitted through a sample for a given wavelength. [database_cross_reference: ISBN:038733341X]
PFU Plaque-forming unit. A measure of viable infectious entities (e.g. viral particles or group of particles) in the specimen or product defined as the smallest quantity that can produce a cytopathic effect in the host cell culture challenged with the defined inoculum, visible under the microscope and/or to the naked eye as a plaque. A number of plaque forming units (PFU) per unit volume is a conventional way to refer the titer of an infective entity in a specimen or preparation.

ug/dl A unit of mass concentration defined as the concentration of one microgram of a substance per unit volume of the mixture equal to one deciliter. The concept also refers to the unit of mass density (volumic mass) defined as the density of substance which mass equal to one microgram occupies the volume one deciliter.
ug/l A unit of mass concentration defined as the concentration of one microgram of a substance per unit volume of the mixture equal to one liter. The concept also refers to the unit of mass density (volumetric mass) defined as the density of a substance which mass equal to one microgram occupies the volume of one liter.
