Anti-brush border antibody

Anti-BBA (ABBA) is a heterophile antibody which has been seen in IFA tests using animal kidney, reacting against the brush borders of proximal renal tubules. We use the FLUORO-KIT test system with cryostat sections of rat kidney and stomach, and or rat liver as the substrate for some IFA tests at a beginning dilution of patient's serum of 1:20. The use of animal tissue otherwise avoids interference from HLA and/or blood group Abs that may occur were human substrate used. Incidental Abs may show up in this system such as ASMA, APCA, ANA, ARA, anti-canalicular Ab, anti-liver cell membrane Ab, and anti-ribosomal Ab

Associations with undetectable Ab:

  • normalcy

Associations with elevated levels:

  • uncertain whether any actual disease associations
