Description

Swelling—also called edema—occurs when excess fluid gets trapped in the body’s tissues. This can be due to a wide range of conditions, from mild inflammation to more serious issues with the heart, kidneys, liver, or thyroid.

This specialized blood panel is designed to help uncover the underlying cause of fluid retention by evaluating multiple organ systems and inflammatory markers.

Why This Panel Matters

This test provides key insights into several common causes of swelling, including:

  • Heart dysfunction
  • Kidney impairment
  • Liver abnormalities
  • Thyroid imbalance
  • Inflammatory conditions

Common Symptoms That May Warrant Testing

  • Swollen feet, ankles, hands, or face
  • Puffiness around the eyes
  • Sudden or unexplained weight gain
  • Joint stiffness
  • Shortness of breath (possible heart or lung-related)

Biomarkers Included & Clinical Significance

BNP (B-type Natriuretic Peptide)

  • What it does: Measures a hormone released by the heart when it’s under strain.
  • Why it matters: Elevated BNP is a key indicator of heart failure, a major cause of fluid buildup.

C-Reactive Protein (CRP)

  • What it does: Detects levels of inflammation in the body.
  • Why it matters: High CRP suggests systemic inflammation or infection, both of which can contribute to swelling.

CBC (Complete Blood Count with Differential)

  • What it does: Evaluates red and white blood cells, hemoglobin, hematocrit, and platelets.
  • Why it matters: Can reveal anemia, infection, or blood disorders that may contribute to systemic fluid retention.

CMP (Comprehensive Metabolic Panel)

  • What it does: Analyzes electrolytes, kidney function, liver enzymes, and glucose.
  • Why it matters: Screens for kidney disease, liver dysfunction, and metabolic imbalance—common causes of swelling.

Creatinine + Cystatin C

  • What it does: Two sensitive markers of kidney function.
  • Why it matters: Impaired kidneys often fail to remove excess fluid, leading to edema.

Plasma Viscosity

  • What it does: Measures the thickness of your blood.
  • Why it matters: Elevated viscosity may reflect inflammatory or vascular conditions that contribute to swelling.

TSH (Thyroid-Stimulating Hormone)

  • What it does: Checks for thyroid hormone imbalance.
  • Why it matters: Low thyroid function (hypothyroidism) is a well-known cause of puffiness and fluid retention.

Urine Protein (Random Sample)

  • What it does: Detects abnormal protein levels in the urine.
  • Why it matters: Proteinuria may indicate kidney damage or nephrotic syndrome, both linked to significant edema.

Fasting Requirements

No fasting is required for this panel. You may eat and drink normally before your appointment.

Who Should Consider This Panel?

  • Individuals experiencing unexplained swelling or puffiness
  • Those with known kidney, heart, liver, or thyroid issues
  • Patients with sudden weight gain or bloating
  • Anyone being evaluated for fluid retention or edema
