Candida Antibody Panel (IgG, IgA, IgM) for Brain Fog

Blood test measuring immune response to Candida. Elevated IgG indicates past exposure (common, non-specific). Elevated IgA/IgM indicates active mucosal immune response (more clinically relevant). Used alongside stool analysis and OAT for comprehensive evaluation.

Quick Answer

Blood test measuring immune response to Candida. Elevated IgG indicates past exposure (common, non-specific). Elevated IgA/IgM indicates active mucosal immune response (more clinically relevant). Used alongside stool analysis and OAT for comprehensive evaluation.

Availability

request through clinician

Result Context Range

IgG <1.0 U/mL, IgA/IgM <0.5 U/mL (varies by lab)

What This Helps Measure

Blood test measuring immune response to Candida. Elevated IgG indicates past exposure (common, non-specific). Elevated IgA/IgM indicates active mucosal immune response (more clinically relevant). Used alongside stool analysis and OAT for comprehensive evaluation.

Which theories this can evaluate

This measurement is most useful when your pattern already suggests why it belongs in the workup.

What It Does Not Prove

One biomarker rarely settles the full question on its own. It is most useful when the pattern already suggests why it matters.

Visual Guide

Candida Antibody Panel (IgG, IgA, IgM) visual guide

How To Prepare

  • •Confirm timing (fasting vs non-fasting) with your clinician or lab before the draw.
  • •Bring your medication/supplement list and note recent illnesses.
  • •Use the same lab when possible for trend consistency.

How To Use This Test Well

Step 1

Book correctly

Request Candida Antibody Panel (IgG, IgA, IgM) with required timing/prep (fasting and time-of-day when relevant).

Step 2

Capture the result exactly

Save numerical value, units, lab reference interval, and collection time.

Step 3

Interpret with pattern context

Compare results against symptom timing and related markers before changing plan.

What To Watch For

  • →Lab reference ranges and optimal targets are not the same concept.
  • →Recent illness, menstrual phase, sleep disruption, and medications can shift values.
  • →Trend over time often matters more than one isolated value.

Result Context

normal

Within lab range; compare with your target context (IgG <1.0 U/mL, IgA/IgM <0.5 U/mL (varies by lab)).

Result may be acceptable but still needs symptom correlation and trend review.

borderline

Near thresholds or inconsistent with symptoms.

Consider repeat testing, timing factors, and related markers before conclusions.

abnormal

Outside expected range or clearly discordant with baseline.

Use clinician-guided follow-up and structured differential workup.

What To Do Next

  • •Save the result with date and symptoms from the same week.
  • •Review alongside related tests instead of interpreting in isolation.
  • •Use one concrete next step in your panel plan.
