Nov 16, 2023 · The serum sodium (Na) test measures the amount of sodium in the blood. Like other electrolytes, sodium helps your nerves and muscles work properly. Normally, excess sodium in the things you eat and drink is excreted by the kidneys.

Nov 7, 2024 · Interpreting blood tests is best left to a physician, but it may be helpful to know what a test looks for. This article breaks down common blood tests and explains what they mean.

Serum is obtained from clotted blood that has not been mixed with an anticoagulant (a chemical that prevents the clotting of blood). This clotted blood is then centrifuged, yielding serum, which contains two types of protein: albumin and globulin.

A blood chemistry panel is another common test used to evaluate a variety of components. Usually, it consists of about 7-25 tests. The information below is meant to provide an overview of these tests.

Nov 9, 2021 · Chemistry panels are groups of tests that are routinely ordered to determine a person’s general health status. They help evaluate, for example, the body’s electrolyte balance and/or the status of several major body organs. The tests are performed on a blood sample, usually drawn from a vein.

Serum (/ ˈ s ɪər ə m /) is the fluid and solvent component of blood which does not play a role in clotting. [1] It may be defined as blood plasma without the clotting factors , or as blood with all cells and clotting factors removed.

Sep 6, 2022 · The serum chemistry profile, composed of a battery of tests, is readily available to clinicians through in-house testing or veterinary reference and diagnostic laboratories. A chemistry profile allows for evaluation of several body systems and assessment of metabolic, acid-base, or electrolyte disturbances.

Serum is the supernatant fluid when clotted blood has been centrifuged. It is the best specimen for most clinical chemistry laboratory tests because of its specific characteristics. Here are the reasons why serum is the best specimen.

Dec 15, 2019 · In blood, the serum is the fluid and solute component of blood after clotting. It is neither a blood cell (serum does not contain white blood cells – leukocytes, or red blood cells – erythrocytes), nor a clotting factor; it is the blood plasma not including the fibrinogens.

Sep 4, 2022 · Serum is the liquid fraction of whole blood that is collected after the blood is allowed to clot. The clot is removed by centrifugation and the resulting supernatant, designated serum, is carefully removed using a Pasteur pipette.
