Can trace protein be found in urinalysis during menses?

The answer is: no

Trace protein levels are not typically elevated during menses and cannot be found in urinalysis during this time. Trace protein levels are often associated with certain medical conditions, such as kidney dysfunction or some forms of urinary tract infection. During menstruation, the sloughing off of the uterine lining and associated hormonal changes may cause some variations in urine composition, but the presence of trace proteins is not a usual observation solely due to menstruation.
