What is a Sodium Heparin Tubes?

Sodium heparin is a salt of heparin, as was mentioned in the preceding section. An ionizable medication and a counter-ion combine to form a neutral substance known as a salt. For example, in NaCl, or common table salt, the ion is Na+, and the counter-ion is Cl-. Table salt is created when the positively charged sodium ion is combined with the negatively charged chloride ion.
