Capillary leak syndrome laboratory findings

Introduction

Overview

Overview

All patients with capillary leak syndrome have an elevated hematocrit concentration during an attack, resulting in hemoconcentration. Moreover, elevated WBCs, elevated BUN, elevated creatinine, elevated creatine kinase and hypoalbuminemia without albuminuria may also be seen.

Laboratory Findings

Laboratory Findings

Capillary leak syndrome presents with the following lab abnormalities:

  • Hemoconcentration (Increased hemoglobin and hematocrit)
  • Elevated WBCs
  • Elevated Blood urea nitrogen (BUN)
  • Elevated creatinine
  • Elevated creatine kinase
  • Hypoalbuminemia without albuminuria[1][2]
  • Blood and urine cultures to rule out sepsis
  • Serum tryptase to rule out anaphylaxis
  • Serum immunofixation electrophoresis to determine the presence of paraprotein
  • IgG kappa supports the diagnosis of systemic capillary leak syndrome


The degree and duration of hypotension and edema may vary in patients with systemic capillary leak syndrome, and therefore, the severity scale may aid in the diagnosis of patients with recurrent episodes of swelling.[3]

SCLS Severity Scale
Grade Hemoconcentration Hypoalbuminemia Treatment
1a Hgb ≤ 3 g/dL Albumin ≤ 0.5 g/dL Oral fluids
1b Hgb ≥ 3 g/dL Albumin ≥ 0.5 g/dL Oral fluids
2 IV fluids, no hospitalization
3 IV fluids, ICU
4 ICU
