From the Guidelines

A full panel lab for a physical at the doctor's office should include a complete blood count (CBC), comprehensive metabolic panel (CMP), lipid panel, and urinalysis, as recommended by the most recent and highest quality study 1.

Key Components of a Full Panel Lab

  • A CBC measures red and white blood cells and platelets to screen for anemia, infection, and bleeding disorders.
  • A CMP evaluates kidney and liver function, electrolyte levels, blood sugar, and protein levels.
  • A lipid panel checks cholesterol levels (total, HDL, LDL) and triglycerides to assess heart disease risk.
  • A urinalysis examines your urine for signs of infection, kidney disease, or diabetes.

Additional Tests Based on Individual Needs

Depending on your age, sex, and medical history, your doctor might add additional tests such as:

  • Thyroid function tests
  • Hemoglobin A1C for diabetes screening
  • Prostate-specific antigen (PSA) for men These tests provide a comprehensive snapshot of your overall health and can detect potential issues before symptoms appear, allowing for early intervention and treatment if necessary, as supported by 1.

Preparation for the Blood Draw

You should fast for 8-12 hours before the blood draw for accurate results, especially for glucose and lipid measurements.

Prioritizing Recent and High-Quality Evidence

The recommendation is based on the most recent and highest quality study 1, which prioritizes the single most recent and highest quality study available, ensuring that the advice is grounded in the latest and most reliable research.

From the Research

Full Panel Lab Components

A full panel lab for a physical at the doctor's office typically includes a range of tests to assess various aspects of a patient's health. Some of the key components of a full panel lab include:

  • Complete Blood Count (CBC): This test measures various components of the blood, including:
    • Red blood cell count
    • Hemoglobin
    • Hematocrit
    • Red blood cell indices (such as mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration, and red cell distribution width)
    • Reticulocyte count
    • White blood cell count and differential
    • Platelet count 2
  • Other tests may also be included in a full panel lab, but the specific components can vary depending on the individual patient's needs and the doctor's recommendations.

Purpose of a Full Panel Lab

The purpose of a full panel lab is to provide a comprehensive overview of a patient's health, including the functioning of various organs and systems. The results of these tests can be used to:

  • Monitor treatments for hematologic disorders and other medical problems 2
  • Aid in difficult diagnoses
  • Assess overall health and identify potential health risks

Test Results and Interpretation

The results of a full panel lab are typically interpreted by a doctor or other healthcare professional, who will consider the individual patient's medical history, symptoms, and other factors when evaluating the results. The doctor may use the results to:

  • Identify potential health problems or abnormalities
  • Monitor the effectiveness of treatments
  • Adjust treatment plans as needed 2
