Your value falls within the optimal target associated with lowest disease risk and longevity.

Standard Reference Interval

70 - 180 nmol/L

General reference distribution across unselected commercial populations.

Optimal Longevity Target

100 - 160 nmol/L

Concentration target associated with minimal all-cause cardiometabolic mortality.

Molecular Mechanism & Clinical Purpose

Cofactor for pyruvate dehydrogenase (PDH), alpha-ketoglutarate dehydrogenase, and transketolase in pentose phosphate pathway.

Differential Diagnosis

Elevated Levels (Vit B1 / TDP High)

  • •High-dose thiamine supplementation

Low Levels (Vit B1 / TDP Low)

  • •Wernicke encephalopathy and Korsakoff syndrome
  • •Wet/dry beriberi
  • •Chronic alcoholism and malnutrition
  • •Severe lactic acidosis

Technical Reference & Deep Dive

Biochemistry & Enzymatic Pathways
At the molecular level, Whole Blood Thiamine Diphosphate (Vit B1 / TDP) is critically involved in mitochondrial glucose catabolism. Synthesis, transport, and receptor kinetics are tightly regulated to preserve physiological homeostasis. Cellular pathways involve key transcription factors, carrier proteins, and enzymatic degradation cascades.
Longevity Risk Architecture & Epidemiology
Deficiency impairs cellular aerobic ATP generation, causing acute lactic acidosis, Wernicke-Korsakoff syndrome, and beriberi.
Pre-Analytical Caveats & Diagnostic Workup

Pre-Analytical Considerations:

Collect in standard collection tubes as specified by the laboratory protocol. Avoid hemolysis and process serum/plasma promptly within 2 hours. Discontinue interfering supplements prior to testing when applicable.

Reflexive Testing Protocol:

  • Confirmatory testing and secondary biomarker panel evaluation for Vit B1 / TDP
  • Targeted imaging or functional organ assessment related to mitochondrial glucose catabolism
  • Comprehensive metabolic and inflammatory baseline panel (CMP, CBC, hs-CRP)
