What is plasma osmolarity?

What is plasma osmolarity?

Solutes in plasma: Plasma osmolarity is a reflection of various salts in plasma. It can be measured directly, usually by freezing point depression, or commonly calculated using the following equation = 2[na+] + [glucose]/18 + [ BUN ]/2.8 where [glucose] and [bun] are measured in mg/dl. Normal value is 270-310 milli-osmoles per kilogram. ...Read more

What is plasma acth?

What is plasma acth?

Pituitary hormone: Hi. ACTH is a hormone from the pituitary gland that travels by the bloodstream to the adrenal glands and stimulates cortisol production (and to a lesser extent, aldosterone). The cortisol feeds back to the pituitary to regulate ACTH release (also effects on hypothalamic CRH, but we'll keep it simple). ACTH positive feedforward & cortisol negative feedback works beautifully. Diseases can affect it. ...Read more

What is plasma osmolarity? Plasma osmolality?

Conc. electrolytes.: These refer to the concentration of electrolytes in the body/plasma, or the electrolyte-water balance. These measure the same thing, only that osmolality is the number of osmoles per kilogram of solvent or osm/kg, while osmolarity is the number of osmoles per liter of solution or osm/ltr. Osmolality excludes the solute, while osmolarity includes it, so osmolality has a slightly higher reading. ...Read more

What is plasma acth and how is it performed?

What is plasma acth and how is it performed?

Pituitary hormone: Acth comes from the pituitary and regulates adrenal cortisol. It is measured in an immunoassay. Acth is a small peptide, broken down quickly in plasma, and is tricky to assay; results can be unreliable if the sample is not processed properly. It is measured in the work up of adrenal and/or pituitary disorders, such as cushing's disease or pituitary deficiency. ...Read more

If RBCs carry oxygen, what does plasma carry?

If RBCs carry oxygen, what does plasma carry?

Proteins, etc: Plasma is a yellowish liquid portion of whole blood after red blood cells, white blood cells and platelet are removed by centrifuge. It contains many proteins, hormones, and electrolytes essential for our life. For proteins, it includes immunoglobulin (for immunity), clotting factors (for hemostasis reducing bleeding), lipoproteins (carry lipid), enzymes and hormones, etc. ...Read more

What is plasma acth cortisol response?

What is plasma acth cortisol response?

Test adrenal fxn.: This test is to check on whether or not your adrenal glands are working right. The acth action is to increase production and release of corticosteroids.
