Hi and welcome to HCM.
These are nonspecific findings of any inflammatory process in our body. Most common are respiratory and urinary infections. And it can be caused by tonssilopharyngitis of course.Proteins
in urine can be sign of kidney
glomerular damage or uroinfection but sometimes can be found in healthy people. I suggest to take antibiotics for throat infection
and repeat blood tests in 2-3 weeks. WIsh you good health.
