Blood culture bottle: Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms: Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms. [2] Blue ("light blue") Sodium citrate (weak calcium chelator ...
These tubes should be used with care when measuring drug or hormone levels because the drug or hormone may diffuse from the serum into the gel, causing a reduction in measured level. The gel in SST II tubes (which appears slightly less opaque) is supposed [ weasel words ] to have less effect on drug levels in serum.
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]
Two complex chimpanzee blood group systems, V-A-B-D and R-C-E-F systems, proved to be counterparts of the human MNS and Rh blood group systems, respectively. Two blood group systems have been defined in Old World monkeys: the Drh system of macaques and the Bp system of baboons, both linked by at least one species shared by either of the blood group systems.

U.S. Army veteran Matt Schermerhorn couldn’t give blood for years because he was stationed in Europe during a deadly mad cow disease scare there. Schermerhorn, 58, is among thousands of people ...
The blood is collected aseptically into a sterile container or blood bag and then allowed to clot. The normal method of collection is cardiac puncture. This minimizes the danger of serum contamination with micro-organisms from the fetus itself, and the environment, while maximizing the volume of blood collected.
whole blood: venipuncture: requires phlebotomist to collect Dried blood spot: gives high quality DNA and RNA Fingerstick: stores easily for years at room temperature organ tissue gives high quality DNA, RNA, Mitochondrial DNA, and source of disease Biopsy: many uses shared with blood; also suitable for proteomic analysis; may be difficult to ...
