Mass concentration (g/dL or g/L) is the most common measurement unit in the United States. Is usually given with dL (decilitres) as the denominator in the United States, and usually with L (litres) in, for example, Sweden. [citation needed]
BUN is an indication of kidney health. The normal range is 2.1–7.1 mmol/L or 6–20 mg/dL. [1]The main causes of an increase in BUN are: high-protein diet, decrease in glomerular filtration rate (GFR) (suggestive of kidney failure), decrease in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, [5] fever, rapid cell destruction from infections, athletic ...
For example, a methemoglobin concentration of 1.5 g/dL may represent a percentage of 10% in an otherwise healthy patient with a baseline hemoglobin of 15 mg/dL, whereas the presence of the same concentration of 1.5 g/dL of methemoglobin in an anemic patient with a baseline hemoglobin of 8 g/dL would represent a percentage of 18.75%.
PROTEIN/GI/LIVER FUNCTION TESTS: LDH = 100 TP = 7.6 AST = 25 TBIL = 0.7 ALP = 71 Alb = 4.0 ... while standard base excess is the value when the hemoglobin is at 5 g/dl.
Protein: 15 [1] [2] 40, [4] 45 [1] [2] mg/dL ~1% [1] Albumin: 7.8 [5] 40 [5] mg/dL: 0 [6] - 0.7% [6] - corresponding to an albumin (CSF/serum) quotient of 0 to 7x10 ...
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.
On average, each change of 3.3 mmol (60 mg/dL) in average blood sugar levels will give rise to changes of 2% HbA1c and 75 μmol fructosamine values. [6] However, this overemphasizes the upper limit of many laboratories' reference ranges of 285 μmol/L as equivalent to HbA1c 7.5% rather than 6.5%.
An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.
