Does Sodium Citrate have any effect on Rapid Plasma Reagin and/or serum protein electropheresis testing??

Answer 1

Sodium citrate is a white granular powder, saline in taste and soluble in water. Used as an anticoagulant for blood collected for laboratory analysis or used for transfusion.

Rapid plasma reagin (RPR) is a nonspecific serological test for syphilis. The RPR titer is elevated in most patients with syphilis (and falsely elevated in some patients with other diseases). The titer decreases or returns to normal after successful eradication of the disease.

Protein electrophoresis is when you analyze the proteins in the blood serum, albumin and globulin.

I guess sodium citrate would affect the latter but not the former
