Determination of plasma inorganic iodine by neutron activation analysis after ultrafiltration. 1980

H S Aabech, and E Steinnes

A direct method for the determination of plasma inorganic iodine (PII) is described. After separation from protein-bound iodine by ultrafiltration, the PII is determined by neutron activation analysis. In material from thirty-nine normal subjects a range of 7.9-88.3 nmol/l was observed, with a mean value of 31.5 nmol/l.

D007455	Iodine	A nonmetallic element of the halogen group that is represented by the atomic symbol I, atomic number 53, and atomic weight of 126.90. It is a nutritionally essential element, especially important in thyroid hormone synthesis. In solution, it has anti-infective properties and is used topically.	Iodine-127,Iodine 127

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D014462	Ultrafiltration	The separation of particles from a suspension by passage through a filter with very fine pores. In ultrafiltration the separation is accomplished by convective transport; in DIALYSIS separation relies instead upon differential diffusion. Ultrafiltration occurs naturally and is a laboratory procedure. Artificial ultrafiltration of the blood is referred to as HEMOFILTRATION or HEMODIAFILTRATION (if combined with HEMODIALYSIS).
