Description

The Calory Function Test measures the body's metabolic rate and how efficiently it burns calories. This test helps in understanding an individual's energy expenditure and is useful for designing personalized diet and exercise plans.

How our test process works!

Step 1

Sample Collection

Vaccinated Phlebotomists collects from syringe in the barcoded vials

Step 2

Sample Storage

Only vaccinated phelbos are assigned orders

Step 3

High Tech Facility

Lab ingests the sample into processing machines which are 100% automated

Step 4

Accurate Digital Reports

The reports are generated by the processing machines and clinically correlated by doctors

Overview

Overview

  • Purpose: Determines the rate at which the body burns calories (Resting Metabolic Rate, RMR) and total energy expenditure (TEE).

  • Used For:

    • Weight management
    • Evaluating metabolic health
    • Diagnosing metabolic disorders
    • Guiding nutritional therapy
  • Methods:

    • Indirect Calorimetry: Measures oxygen consumption and carbon dioxide production.
    • Direct Calorimetry (less common): Measures heat production directly.

 

Risk assessment

Risk Assessment

  • Low Risk: The test is non-invasive.
  • Potential Issues:
    • Discomfort during prolonged mask or hood use for indirect calorimetry.
    • Errors due to incorrect fasting state, medications, or illness.

 

Ranges

Normal Range

  • RMR: Varies by age, gender, weight, and activity level.
    • Example: A 32-year-old male weighing 74 kg may have an RMR of ~1,600–1,900 kcal/day.
  • Deviation from normal indicates:
    • Higher RMR: Hypermetabolism (e.g., thyroid disorders, fever, stress).
    • Lower RMR: Hypometabolism (e.g., hypothyroidism, aging, starvation).

 

Test result interpretation

Interpretation

  • Higher than Normal:
    • Increased caloric needs
    • Potential underlying conditions (e.g., infections, trauma, stress)
  • Lower than Normal:
    • Reduced caloric needs
    • Possible metabolic slowdown, underactive thyroid, or malnutrition
  • Normal Ranges:
    • Suggest balanced metabolism and energy utilization.

 

Sample types

Sample Type

  • Sample Type: Air samples from breathing are analyzed in indirect calorimetry using a metabolic cart or hood.
  • Fasting Requirement: Typically requires a fasting period of 6–8 hours for accurate results.
  • Body Composition Data: May be integrated using tools like bioelectrical impedance analysis (BIA).
