The first reported method for disrupting immune complexes was performed using heat and EDTA.3 This method has proven preferable to other ICD methods for both accuracy and predictability.4 In this process, heat denatures and precipitates the soluble proteins, including the antibodies.
9 sie 2022 · Highly sensitive antigen tests provide rapid cageside confirmation of HWI. Current antigen tests detect a protein found predominantly in the reproductive tract of female heartworms. Antigen is usually detectable by about 6 months post-infection. Testing dogs younger than 6 months is therefore not recommended.
12 sty 2024 · The most common platform for testing dogs and cats for heartworm is an antigen ELISA or lateral flow assay (e.g. IDEXX SNAP® 4Dx®Plus/Heartworm, Heska SoloStep®, Zoetis Witness™ and DiroCHEK®, Abaxis VetScan®, etc.).
1 lip 2020 · Heat treatment of serum has demonstrated improved detection of Dirofilaria immitis antigen in sera of sheltered dogs without knowing the true infection status of the animals and in dogs confirmed experimentally to be infected with heartworm.
26 kwi 2021 · Heat treatment (HT) or chemical treatment to destroy complexes can increase Ag test sensitivity [4, 9, 22, 23]. However, HT protocols require extra laboratory equipment, time, and cost, reducing utility when large numbers of dogs are tested on a daily basis, such as in animal shelters in HW-endemic regions.
