The blood volume is 70 ml/kg body weight in adult males, 65 ml/kg in adult females and 70-75 ml/kg in children (1 year old and over). [5] [6] Total Blood Volume has been measured manually by the use of carbon monoxide (CO) as a tracer for more than 100 years and was first proposed by French scientists Grehant and Quinquaud in 1882.
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"), the ...
Hemoglobin has an oxygen binding capacity between 1.36 and 1.40 ml O 2 per gram hemoglobin, [23] which increases the total blood oxygen capacity seventyfold, [24] compared to if oxygen solely were carried by its solubility of 0.03 ml O 2 per liter blood per mm Hg partial pressure of oxygen (about 100 mm Hg in arteries). [24]
The cerebral blood volume value of gray matter is about 3.5 +/- 0.4 ml/100g, and the white matter is about 1.7 +/- 0.4 ml/100g. The gray matter is nearly twice that of white matter. [3] In both white and gray matter, cerebral blood volume decreases by about 0.50% per year with increasing age. [4]

"Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
In the past to measure blood glucose it was necessary to take a blood sample, as explained below, but since 2015 it has also been possible to use a continuous glucose monitor, which involves an electrode placed under the skin. Both methods, as of 2023, cost hundreds of dollars or euros per year for supplies needed. [citation needed]
In renal physiology, renal blood flow (RBF) is the volume of blood delivered to the kidneys per unit time. In humans, the kidneys together receive roughly 20 - 25% of cardiac output, amounting to 1.2 - 1.3 L/min in a healthy adult. [1] It passes about 94% to the cortex.
