Should glucose erythrocytes leukocytes and protein appear in the urine
saveliy_v [14]

NO, they should not. Erythrocytes, leucocytes, and proteins (albumin) are not small enough to pass through the capillaries of the glomerulus unless there is damage to the glomerulus. However, glucose does pass through into the glomerular filtrate. Nonetheless, glucose is fully reabsorbed back in the proximal convoluted tubule (unless you have severe diabetes).
