Erythrocyte transketolase activity blood test
WebFor many years our group used erythrocyte transketolase activity (TKA, normal range 42–86 mU/L/m in.) with thiamin pyrophosphate effect (TPPE) as described by Massod, McGuire, and Werner (1971). The first part of the test is the baseline transketolase activity (TKA). The reaction is repeated after the addition of TPP. WebThiamine deficiency may be assessed clinically by an abnormally low specific erythrocyte transketolase activity and/or by abnormally large activation by thiamine diphosphate in vitro (or 'TPP effect'). In the present investigation, we report erythrocyte transketolase activation by TPP in acute alcoh …

When rats are fed a thiamin deficient diet, the erythrocyte TPP level falls more rapidly than the erythrocyte transketolase activity. After 8 days, the level of TPP in the erythrocytes of deficient animals was 10% of the level in pair-fed controls.

WebMay 10, 2024 · Deficiency leads to decreased transketolase activity in red blood cells (erythrocytes) and increases pyruvic acid in the blood, which, in turn, is not converted to acetyl-CoA and is unable to enter the Krebs cycle (for aerobic oxidative metabolism). Thus, there is a buildup of pyruvic acid, which is metabolized anaerobically to lactic acid. [3, 9] WebTreatment for Erythrocytosis. Erythrocytosis is when you have more red blood cells than normal.
