DIAGNOSTIC TEST 140

THSD7A Antibodies (IgG)

Diagnostic test for antibodies against THSD7A. For suspicion of primary membranous nephropathy (PMN).

Indication

Suspicion of primary membranous nephropathy (PMN).

Sample material

Serum

  • Minim. volume: 0,5 mL

Transport

Within Sweden

  • room temperature

International

  • cold

Method

Cell-based assay (CBA), Indirect immunofluorescence (IIF)

Reference interval

<1:10 negative

Result

Results are reported as negative or positive. Positive results will be titrated.

Interpretation

Antibodies against THSD7A have been reported to occur in about 10% of the anti-PLA2R negative cases with membranous nephropathy (PMN). The antibodies are primarily IgG4 subclass and have high disease specificity. Antibody titers are associated with disease activity and follow the degree of proteinuria.
