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 ...
Lactic acidosis refers to the process leading to the production of lactate by anaerobic metabolism. It increases hydrogen ion concentration tending to the state of acidemia or low pH. The result can be detected with high levels of lactate and low levels of bicarbonate. This is usually considered the result of illness but also results from ...
During blood pressure check, there's a right way and wrong way to hold your arm, study finds. Blood pressure readings may not be accurate unless a person’s arm is positioned correctly, a new ...
Folate deficiency. Folate deficiency, also known as vitamin B9 deficiency, is a low level of folate and derivatives in the body. [1] This may result in megaloblastic anemia in which red blood cells become abnormally large, and folate deficiency anemia is the term given for this medical condition. [3] Signs of folate deficiency are often subtle. [4]
ECGs are normally printed on a grid. The horizontal axis represents time and the vertical axis represents voltage. The standard values on this grid are shown in the adjacent image at 25mm/sec: [57] A small box is 1 mm × 1 mm and represents 0.1 mV × 0.04 seconds. A large box is 5 mm × 5 mm and represents 0.5 mV × 0.20 seconds.
Time zones of the world. A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.
Potassium-40 (40K) is a radioactive isotope of potassium which has a long half-life of 1.25 billion years. It makes up about 0.012% (120 ppm) of the total amount of potassium found in nature. Potassium-40 undergoes three types of radioactive decay. In about 89.28% of events, it decays to calcium-40 (40 Ca) with emission of a beta particle (β ...
