Difference Between Plasma and Serum

Difference between Serum and Plasma

The culture and expansion of human cells for clinical use requires the presence of human serum or plasma in culture media. Although these supplements have been extensively characterized in their chemical composition, only recently it has been possible to provide by high throughput protein analysis, a comprehensive profile of the soluble factors contributing to cell survival. This study analyzed and compared the presence of proteins including chemokines, cytokines and soluble factors in six different types of media supplements: serum, plasma, recalcified plasma, heat inactivated serum, heat inactivated plasma and heat inactivated recalcified plasma. Serum, plasma, recalcified plasma, and heat inactivated supplements were prepared from ten healthy subjects. The levels of soluble factors were measured in each sample using a multiplexed ELISA assay and compared by Eisen hierarchical clustering analysis.

Can we calculate the hormones concentration from plasma and if we have to samples of same blood having plasma and serum. Very good effort however in differences between serum and plasma you stated in No. It is written there that Plasma contain antibodies that fight foreign agents in the host body. Save my name and email in this browser for the next time I comment. Characteristics Serum Plasma 1. Definition Serum is the liquid part of the blood after the coagulation. Plasma is a clear and yellowish fluid part of the blood.

Gundersen Clinic La Crosse, Wis. To the Editor. The difference they observed is larger than the previously established value. The reevaluation report 1 suggested that the increased difference was due to a higher concentration of disodium EDTA, now routinely used in blood collection tubes. Samples were collected with Vacutainer Systems collection tubes, Becton-Dickinson, Rutherford, NJ and the collection order of the paired serum and plasma specimens was alternated. Disodium EDTA tubes final concentration, 4.

Gifford Lum, M. Raymond Gambino, M. Heparinized plasma and serum were assayed simultaneously, and a t test for paired or dependent values was used to evaluate the statistical significance of any difference found. No significant difference between serum and plasma was found for alanine aminotransferase, aspartate aminotransferase, amylase, total bilirubin, BUN, calcium, CO2, creatine phosphokinase, creatinine, or glucose. Method-dependent differences were found for chloride, cholesterol, and lactic dehydrogenase. Statistically significant but clinically unimportant differences were found for alkaline phosphatase, albumin, phosphorus, sodium, triglyceride, and uric acid. Statistically significant and clinically important differences were found for potassium and total protein.

The levels of specific, circulating miRNAs in blood have been shown to associate with various pathological conditions including cancers. These miRNAs have great potential as biomarkers for various pathophysiological conditions. Using serum and corresponding plasma samples from the same individuals, we observed higher miRNA concentrations in serum samples compared to the corresponding plasma samples. The difference between serum and plasma miRNA concentration showed some associations with miRNA from platelets, which may indicate that the coagulation process may affect the spectrum of extracellular miRNA in blood. Several miRNAs also showed platform dependent variations in measurements. Our results suggest that there are a number of factors that might affect the measurement of circulating miRNA concentration. Caution must be taken when comparing miRNA data generated from different sample types or measurement platforms.

Difference Between Plasma and Serum

Human plasma and serum are widely used matrices in clinical and biological studies. However, different collecting procedures and the coagulation cascade influence concentrations of both proteins and metabolites in these matrices. The effects on metabolite concentration profiles have not been fully characterized.

Stewart, T. J Exp Med 1 February ; 17 2 : — Apparently, then, we are confronted with this result,—that citrate plasma which causes little or no constriction of the stretched artery ring, little or no slowing of the flow through the frog perfusion preparation, while the corresponding serum produces a marked effect on both preparations, will affect the intestine or uterus preparation practically in the same way as the corresponding serum. Hirudin plasma and serum exert on the intestine and uterus preparations practically the same effect, causing a marked increase of tone. On the artery ring preparation, there is a difference although it is not so strongly marked as in the case of the citrate material.

Plasma is that part of the blood, which contains blood clotting agent called as fibrinogen , while serum is the fluid part of the blood and does not contain clotting agent. The plasma and serum can be extracted from the centrifugation of blood. The serum is obtained after the clotting of blood, while plasma can be obtained before the coagulation of the blood. Centrifugation separates the blood components by its weight, size, and density.

Serum vs. Plasma: What’s the Difference?

View Cart Checkout. For some scientists, the difference between serum and plasma is just nomenclature. Plasma is the liquid that remains when clotting is prevented with the addition of an anticoagulant. See All Available Serum Products. See All Available Plasma Products. The clotting process activates a cascade of proteases, which results in the conversion of prothrombin to thrombin, an enzyme that converts fibrinogen into fibrin to clot blood. Platelets are activated in the process and release a set of compounds, which naturally alters proteins in the serum.

Blood plasma is a yellowish liquid component of blood that holds the blood cells of whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood disorders. Blood plasma is separated from the blood by spinning a tube of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The blood plasma is then poured or drawn off. Blood serum is blood plasma without clotting factors.
