Determination of a patient's blood volume status is an important and sometimes challenging area of clinical medicine. Fluid balance and circulation are essential in helping to maintain hemodynamic homeostasis. Physiologically, a balance exists between the intake of food and liquids versus output through respiration, urine, feces, and skin. In health, our bodies can efficiently regulate this
— -- Question: What is the difference between a finger stick test and a plasma test? Answer: A finger stick glucose test is exactly what it is: it's a finger stick.So a little poke is make in
The kidneys play a vital role in the excretion of waste products and toxins such as urea, creatinine and uric acid, regulation of extracellular fluid volume, serum osmolality and electrolyte concentrations, as well as the production of hormones like erythropoietin and 1,25 dihydroxy vitamin D and renin. The functional unit of the kidney is the nephron, which consists of the glomerulus
For instance, clotting depletes fibrinogen and releases potassium during platelet lysis. Therefore, potassium is higher in serum compared to plasma, and total protein is lower in serum than in plasma. Similarly, drug levels in heparinized plasma may differ from serum. If the drug is bound to fibrinogen, plasma level would be higher than in serum.
Serum sickness. Serum sickness is a reaction that is similar to an allergy. The immune system reacts to medicines that contain proteins used to treat immune conditions. It can also react to antiserum, the liquid part of blood that contains antibodies given to a person to help protect them against germs or poisonous substances.
serum bilirubin." I' A few other methods for the determination of blood or serum bilirubin have been described. but none is yet widely used in clinical chemistry laboratories. Spectrophotometric methods These methods differ in whether the absorbance is measured with or without pre-dilution of the scrum in a suitablc bufer. and in the number and
A key difference between plasma and serum is that plasma is liquid, and serum is fluid. While most of the components are the same for both plasma and serum, plasma contains fibrinogen which is absent in serum.

The clot is removed by centrifugation and the resulting supernatant, designated serum, is carefully removed using a Pasteur pipette. Plasma is produced when whole blood is collected in tubes that are treated with an anticoagulant. The blood does not clot in the plasma tube. The cells are removed by centrifugation.

Plasmapheresis is the process healthcare providers use to obtain plasma from blood. Many times, providers do plasmapheresis to obtain donor plasma — plasma from healthy people that providers use when treating certain medical conditions. Plasma exchange is when providers use plasmapheresis to replace someone’s plasma.
The biochemical profile of whole blood, serum and plasma is a complex composition of over one thousand small molecules representing multiple biochemical families. In this study, we compared the levels of each compound detected in five different sample types as well as the relative ranges of these biochemicals . Both aspects are important for
What is difference between serum & plasma in biology? Serum is the liquid that remains after the clotting of blood. Whereas, plasma is the liquid that remains when anticoagulant is added to prevent clotting. A transparent, straw-coloured, liquid portion of the blood. An undiluted fluid, the extracellular portion of blood.
Serum osmolality is affected by the concentration of blood chemicals like chloride, sodium (Na), proteins, bicarbonate, and glucose. The blood urea nitrogen (BUN) measurement is important for calculating serum osmolality. Specific therapies and toxins that affect an individual’s fluid balance should also be evaluated with serum osmolality.

Your body needs potassium to function normally. It’s vital to the functioning of nerve and muscle cells. A normal potassium level is between 3.6 and 5.2 millimoles per liter. IMfHn.
