What is plasma osmolarity? Plasma osmolality?

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 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 the difference between plasma renin activity (pra) vs plasma renin concentration (prc)?

What is the difference between plasma renin activity (pra) vs plasma renin concentration (prc)?

See below:: Not all proteins are functionally active, especially in the case of enzymes. Discordance between renin concentration (prc) and renin activity (pra) allows detection of adrenal tumors. See this site for more info. http://www.ncbi.nlm.nih.gov/pubmed/15080782. ...Read more

Risks of kidney transplant and plasma exchange?

Risks of kidney transplant and plasma exchange?

Not very harmful: If someone spoke to you about plasma exchange, then the issue is the presence of anti-donor antibodies in the recipient. The procedure removes the plasma containing the antibodies. The procedure is used either at the time (or just before) the transplant to prevent rejection in sensitized patients. Or, after the transplant if antibody mediated rejection has occurred. ...Read more

What's the purpose of monitoring glycosylated hemoglobin levels in diabetes?

What's the purpose of monitoring glycosylated hemoglobin levels in diabetes?

A Better average: Sugar level fluctuates significantly throughout the 24 hours--dependent on intake and activities level, thus not a reliable measure of control using random testing. Glycosylated hemoglobin (a1c) is a by product of sugar metabolism and higher sugar over time=higher a1c. A1c testing is not dependent on fasting. It is an "average" measurement, thus more reliable. Consult doc. Good luck. ...Read more

What is the consequences of high count of white blood cells in renal failure?

High White Count: A high white count usually indicates that a patient has an infection. When your kidneys fail you are more susceptible to infection for a whole bunch of reasons. The consequence is not so much that your blood count is high, but that you likely have an undiagnosed infection and this needs to be investigated by your dialysis doctor/nephrologist or your primary care doctor. ...Read more

Are cholesterol molecules located in the plasma membrane of human red blood cells?

Are cholesterol molecules located in the plasma membrane of human red blood cells?

Yes: There is a mixture of proteins, phospholipids, and cholesterol in the cellular membrane of red blood cells. This allows the red cells to maintain their flexibility so they can squeeze through small blood vessels. ...Read more

Can 14 percent of plasma cells mean mgus?

Can 14 percent of plasma cells mean mgus?

Usually lower: In MGUS (monoclonal gam myopathy of unknown significance) the plasma cells usually comprise less than 10% of the marrow. In MGUS there are no lyric (destructive) lesions in the bones. A hematologist is the doctor to see, but even gopher may have difficulty distinguishing MGUS from smoldering myeloma. ...Read more

Range of creatinine excretion in random urine sample in CKD patient?

Range of creatinine excretion in random urine sample in CKD patient?

Difficult to answer.: Cr varies depending on a host of factors and how you might be measuring and the degree of ckd. Typical production of cr is about 16mg/kg/day in females and about 20% more in males due to larger muscle mass. If the kidneys are at steady state excretion equal s production. ...Read more
