Thanks for your question.
After going through your question, I can understand your concern.
There are many different causes for presence traces of protein in urine
- Urinary infection.

If there is no diabetes, Hypertension, fever you can ignore the finding, there is no need of any further evaluation as all other Kidney parameters are acceptable considering your age.
You need not alter your current protein intake.
If there is presence of diabetes or Hypertension then it may be indicator for need for further evaluation.
In that case following investigations may be advisable -
- Fundoascopy to rule out diabetic and hypertensive retinopathy
- 24 hour urine albumin /protein excretion or early morning spot urine albumin creatinine ratio.
of abdomen and pelvis for Kidney size, shape, echotexture.
