first off you need to know that glomerular filtrate is plasma that has entered Bowman's capsule. Now the reason why red blood cells are normally absent from the glomerural filtrate is because they are to big to pass into the Bowman's capsule.

red blood cells
The lamina densa is a component of the glomerular basement membrane (GBM) in the renal corpuscle. It provides structural support and acts as a filtration barrier, preventing the passage of large molecules like proteins from the blood into the glomerular filtrate. It also helps maintain the integrity and function of the renal corpuscle by separating the glomerular endothelial cells and podocytes.
proteins and cells remain in the blood
The glomerular tubular function is to filter the blood plasma and create urine by reabsorbing essential substances such as water, electrolytes, and nutrients, while also secreting waste products and excess substances from the blood into the urine for excretion. It plays a crucial role in maintaining the body's fluid balance and eliminating waste products.

It does not contains the white or red blood cells. It does not contain the proteins also. It is abnormal to find the proteins in this filtrate.
Not normally - red blood cells are quite large and should be above the glomerular filtration size threshold. Blood in the renal filtrate will by default result in blood in the urine due to an inability of the kidney to reabsorb it and this is pathlogic.

Conditions which allow the red blood cells and protein to enter the filtrate are renal infections, kidney infections, diabetes, hypothyroidism, jaundice, and Glomerulonephritis. The reasons of red blood cells entering the filtrate can be various and dangerous.
. Since proteins are very large molecules (macromolecules), they are not normally present in measurable amounts in the glomerular filtrate or in the urine. The detection of protein in urine, called proteinuria may indicate that the permeabilityof the glomerulus is abnormally increased. This may be caused by renal infections or it may be caused by other diseases that have secondarily affected the kidneys such as diabetes mellitus, jaundice, or hyperthyroidism.
