Hematology & CBCNeuronal Somatic Cytoplasm Injury

Plasma UCH-L1 (UCH-L1)

Deubiquitinating cysteine protease abundantly expressed in the neuronal perikaryon (soma), comprising 1% to 2% of total brain soluble protein.

Standard Range<300 pg/mL (baseline), acute surge in TBI
Optimal Longevity<100 pg/mL
Measurement Unitpg/mL

Standard vs. Optimal Reference Rangespg/mL

Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.

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

Standard Reference Interval

<300 pg/mL (baseline), acute surge in TBI

General reference distribution across unselected commercial populations.

Optimal Longevity Target

<100 pg/mL

Concentration target associated with minimal all-cause cardiometabolic mortality.

Molecular Mechanism & Clinical Purpose

Removes ubiquitin from damaged proteins to maintain proteostasis; released massively into blood within 1 hour of neuronal membrane rupture.

Differential Diagnosis

Elevated Levels (UCH-L1 High)

  • •Acute Traumatic Brain Injury (concussion, contusion, diffuse axonal injury)
  • •Severe ischemic stroke with neuronal necrosis

Low Levels (UCH-L1 Low)

  • •Intact neuronal somatic cell membranes
  • •Absence of acute intracranial lesion

Technical Reference & Deep Dive

Biochemistry & Enzymatic Pathways
At the molecular level, Plasma UCH-L1 (UCH-L1) plays an essential physiological role in neuronal somatic cytoplasm injury. Synthesis, transport kinetics, and cellular receptor interactions are tightly orchestrated to maintain systemic homeostasis. Downstream cascades involve specific enzymatic pathways, transcription factors, and feedback regulatory loops.
Longevity Risk Architecture & Epidemiology
FDA-cleared alongside GFAP (Banyan BTI) for rapid rule-out of intracranial lesions on head CT within 12 hours of suspected acute concussion/TBI.
Pre-Analytical Caveats & Diagnostic Workup

Pre-Analytical Considerations:

Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.

Reflexive Testing Protocol:

  • Confirmatory testing and secondary biomarker quantification for UCH-L1
  • Targeted organ system imaging or functional dynamic testing related to neuronal somatic cytoplasm injury
  • Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
