Which of the following is not present in glomerular filtrate?

The glomerulus lining is such that it only allows small molecules, to filter through, like glucose, plasma, ions like sodium and potassium, urea, etc. The larger molecules, like blood cells and protein, cannot pass through the glomerulus. So, proteins are not present in glomerular filtrate. The glomerular filtrate consists,  primarily of water, excess salts (primarily Na+ and K+), glucose and urea.
