Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]

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.
Red blood cells have an average volume of 80–100 femtoliters, but individual cell volumes vary even in healthy blood. [1] Certain disorders, however, cause a significantly increased variation in cell size. Higher RDW values indicate greater variation in size. Normal reference range of RDW-CV in human red blood cells is 11.5–15.4%.
What is a normal blood pressure reading? Updated May 17, 2019 at 1:19 PM When Dr. Oz sat Rachael Ray down for a blood pressure test during a segment of her show, he wasn't entirely pleased with ...
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .

The reference values for a "normal" random glucose test in an average adult are 80–140mg/dl (4.4–7.8 mmol/l), between 140 and 200mg/dl (7.8–11.1 mmol/l) is considered pre-diabetes [citation needed], and ≥ 200 mg/dl is considered diabetes according to ADA guidelines [1] (you should visit your doctor or a clinic for additional tests however as a random glucose of > 160mg/dl does not ...
