Serum and Plasma are essential components of blood. In this blog we compare how to collect both sample types and how to measure analytes in these sample types via ELISA.
PlasmaSample material selectionSerumIn analytical chemistry serum as well as plasma are recommended as sample material of choice. However, blood processing for the generation of serum or plasma is rather different. Whether plasma or serum is the preferable sample material is still controversial ...
Blood phosphorylated tau (p-tau) forms are promising Alzheimer’s disease (AD) biomarkers, but validation in matrices other than ethylenediaminetetraacetic acid (EDTA) plasma is limited. Firstly, we assessed the diagnostic potential of p-tau231 and p-tau
Serum vs Plasma; What’s The Difference ?16 related questions found Why serum is preferred over plasma? In general, serum samples (red top tubes) are preferred for chemistry testing. This is because our chemistry reference intervals are based on serum not plasma. ... For example, LDH, ...
AmitavaDasguptaPhD, DABCC,AmerWahedMD, inClinical Chemistry, Immunology and Laboratory Quality Control, 2014 ▪ Serumprotein electrophoresisperformed using plasma instead of serum produces an additional distinct band between the beta and gamma zones due tofibrinogen, but such a band is absent in subs...
Presence of a Heat-Labile Toxic Protein in Bovine Seminal Plasma A factor, probably a protein, which depresses livability of sperm has been demonstrated in bovine seminal plasma. Its action appears to be directly on sperm and is not due to degradation products of components of the diluent. Grea...
The DXC800 is a modular chemistry analyzer that uses various methods to quantify the concentration of different analytes in serum or plasma. Albumin, ALT, AST and creatinine are measured by enzymatic methods, BUN is measured by an enzymatic conductivity rate method, and cholesterol is measured by...

2024, TrAC - Trends in Analytical Chemistry Citation Excerpt : Arredondo-Damian et al. published a systematic review in 2024 of nine proteomic studies performed on EVs isolated from plasma or serum of patients with T2DM. This review highlights the great potential of proteomic studies of EVs to ...
Total protein can be estimated in fluid, serum, or plasma (ethylenediaminetetraacetic acid [EDTA] or heparinized) by refractometry. Temperature-controlled refractometers calibrated for total protein are preferable to those that read only total solids (see comments under Artifacts).6 Total protein and ...
