- 3Nov 12, '08 by Reno1978serous is usually pale yellow and transparent
serosanguinous would be the same as the above with blood involved, so it usually looks like diluted blood.
I use the terms serous and serosanguinous often....but....
sanguinous would contain mostly blood. I don't think I've ever really used this term when describing any type of drainage, or heard anyone I work with use this term. Usually if there is frank red blood coming out of anywhere on a patient, we state just that.
