Base excess is defined as the amount of strong acid that must be added to each liter of fully oxygenated blood to return the pH to 7.40 at a temperature of 37°C and a pCO 2 of 40 mmHg (5.3 kPa). [ 2] A base deficit (i.e., a negative base excess) can be correspondingly defined by the amount of strong base that must be added.
Other diagnostic tests to determine the level of diabetic control are fructosamine and glycated hemoglobin (GHb) blood tests which can be useful especially if stress may be a factor. [60] While anxiety or stress may influence the results of blood or urine glucose tests, both of these tests measure glycated proteins, which are not affected by them.
Blood tests are also used to assess kidney function. These include tests that are intended to directly measure the function of the kidneys, as well as tests that assess the function of the kidneys by looking for evidence of problems associated with abnormal function. One of the measures of kidney function is the glomerular filtration rate (GFR).
The mean corpuscular volume, or mean cell volume ( MCV ), is a measure of the average volume of a red blood corpuscle (or red blood cell ). The measure is obtained by multiplying a volume of blood by the proportion of blood that is cellular (the hematocrit ), and dividing that product by the number of erythrocytes (red blood cells) in that volume.
67790-6. Io. Thromboelastography ( TEG) is a method of testing the efficiency of blood coagulation. It is a test mainly used in surgery and anesthesiology, although increasingly used in resuscitations in emergency departments, intensive care units, and labor and delivery suites. More common tests of blood coagulation include prothrombin time ...
LOINC. 44734-2, 3097-3. In medicine, the urea-to-creatinine ratio ( UCR[ 1] ), known in the United States as BUN-to-creatinine ratio, is the ratio of the blood levels of urea ( BUN) (mmol/L) and creatinine (Cr) (μmol/L). BUN only reflects the nitrogen content of urea (MW 28) and urea measurement reflects the whole of the molecule (MW 60), urea ...
Heart rate variability. Electrocardiogram (ECG) recording of a canine heart that illustrates beat-to-beat variability in R–R interval (top) and heart rate (bottom). Heart rate variability ( HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval.
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 ...
