The blank solution should be the same pH and of a similar ionic strength as the sample solution. Example: using water for the blank measurement for samples dissolved in TE may result in low 260/230 ratios. A260/A280 Residual phenol or other reagent associated with the extraction protocol. A very low concentration (< 10 ng/μL) of nucleic acid.
v. t. e. 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 ...
Rumack–Matthew Nomogram showing acetaminophen level versus time as a method of interpreting levels and assessing severity and need for treatment. The Rumack–Matthew nomogram, also known as the acetaminophen nomogram, is an acetaminophen toxicity nomogram. It plots serum concentration of acetaminophen against the time since ingestion, in ...
A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.

In a healthy adult male of 75 kg (165 lb) with a blood volume of 5 L, a blood glucose level of 5.5 mmol/L (100 mg/dL) amounts to 5 g, equivalent to about a teaspoonful of sugar. [13] Part of the reason why this amount is so small is that, to maintain an influx of glucose into cells, enzymes modify glucose by adding phosphate or other groups to it.
