Final answer:
Proteinuria, or the presence of protein in urine, is considered a variation of normal in a pregnant woman's urinalysis. It is a physiological condition during pregnancy and is not indicative of Kidney disease or abnormality.
Step-by-step explanation:
The finding in the urinalysis of a pregnant woman that is considered a variation of normal is proteinuria. Proteinuria refers to the presence of protein in urine, which can be a physiological condition seen during pregnancy without indicating kidney damage or disease. It is also seen in cases of vigorous exercise and a condition called orthostatic proteinuria.
Normally, only small traces of protein are found in urine (traces of protein), and higher amounts can suggest glomerular damage; however, during pregnancy, it is not uncommon for mild proteinuria to occur. This is because the increased blood volume and pressure on the kidneys can lead to a small amount of protein leaking into the urine.
By contrast, other findings such as glycosuria (glucose in urine), presence of bacteria in the urine, and ketones in the urine can indicate other conditions that may need further investigation, like diabetes mellitus or infection.
