Lab Analysis

The Lab Analysis tool helps interpret laboratory results, identifying trends and generating clinical alerts for decision support.

Overview​

The module processes structured or unstructured lab data (PDFs, images, pasted text) to:

  • Identify Patterns: Detect subtle changes and trends (e.g., gradual hemoglobin decline).
  • Generate Differentials: Suggest hypotheses based on anomaly combinations.
  • Alert Risks: Flag critical values and potential collection errors or inconsistencies.

How It Works​

1. Data Input​

Paste the report text, upload the PDF, or drag an image into the workspace. The system uses OCR and NLP to extract values.

2. Hybrid Processing​

  • Rule Engine: Compares values against standard reference ranges (adjustable by age/sex).
  • AI Agent: Analyzes the clinical context (if available) to interpret whether a "normal" value is clinically appropriate for that specific patient.

3. Evidence-Based Results​

All analyses include bibliographic references from medical guidelines and current literature.

Key Features​

Report Synthesis​

Instead of an endless list of numbers, Corvus generates a narrative summary of the most relevant findings, grouped by system (e.g., Renal Function, CBC, Electrolytes).

Trend Identification​

The system maps historical results to visualize disease trajectory.

Example: Creatinine stabilization after intervention, or progressive rise in inflammatory markers.

Lab DDx Tool​

The AI suggests explanations for complex lab findings, such as acid-base disorders or multifactorial anemias.

Workflow: Check-to-Accept​

Following the product's core principle, Lab Analysis does not replace the physician:

  1. The System Proposes: AI generates a draft analysis.
  2. The Clinician Reviews: You validate the extracted data and interpretation.
  3. Explicit Acceptance: Use "Add to Plan" or "Copy to Note" after validation.

Best Practices​

  • Provide Context: A creatinine of 1.5mg/dL means different things in a young athlete vs. a frail elderly patient.
  • Validate Extraction: Always check that numbers extracted from PDFs/images match the original document.
  • Consider Timing: Isolated labs are less valuable than historical series.
caution

Attention: Critical values should be validated immediately with the laboratory per your institution's protocol. Corvus is a support tool, not a primary emergency notification system.
