Abstract

Thyopac-4キットを用いてThyroxine (T4) 値を測定すると共に, 同バイアルに少量の患者血清を添加して簡易Free T4 Indexを測定した.本Indexは, 甲状腺機能亢進症では有意の高値を示し, 機能低下症では有意の低値を示すのに対し, 妊娠及びTBG欠損症では正常値を示し, 更に, Free T4の実測値と直線関係をもつ我々のFree T4 Indexとほぼ平行し, またClarkのFree T4 Indexと直線関係にあつて, Free T4濃度をよく反映した.本法の所要血清量は0.5mlに過ぎず, 日常の甲状腺機能検査法として有用と考えられた.
