Microfilaria - Knott test

LABOKLIN Service ID: 2017

Material

EDTA blood 0.5 ml

Method

Knott test

Duration

1 day

Remark

  • Accumulation of the microfilariae of Dirofilaria immitis in the peripheral blood takes place in the evenings (adaptation to the piercing behaviour of vector mosquitoes). This behaviour has not yet been documented for other filarial species, but it is reasonable to take the blood sample after 4 pm.
  • Before departing to South Africa, it is mandatory to do a filtration test.
