What causes colloid osmotic pressure of plasma, except proteins?

I know that plasma proteins(albumin, etc.) cause colloid osmotic pressure of plasma, BUT is there something else that could cause this pressure?

Answer is free haemoglobin, i.e. Hb not trapped in RBCs which is normally not the case, so blood COP is caused by plasma proteins.

Explanation:

Plasma proteins, namely albumin and globulins are responsible for causing COP.

Please note that colloidal osmotic pressure (COP) of blood increases when pH of blood increases.
