One of the welcome side-effects of doing your own urine sediment examination is having easy access to a microscope and some basic lab equipment. This allows you to examine all sorts of things besides urine (Fig. 1).
For me, this is especially useful for peritoneal dialysis fluid samples. I like to look at them myself because I get almost immediate results and a better feel for what is going on within the peritoneum.
WBCs (Fig. 2), bacteria (Fig. 3) and RBCs (Fig. 4) are all readily identified without any special staining, just as in urine.
The urine dipstick works on this fluid as well (Fig. 5).
Of course, this basic examination is only a bedside supplement to formal laboratory evaluation (e.g. WBC differentiation, exact quantification, Gram staining).
