Which of the following is INCORRECT with regards to nerve root/peripheral nerve neoplasia?

A werewolf comes into your practice complaining of being short of breath, especially when exercising (he can talk because, you know, he’s a werewolf). During your history taking you ask if he’s been taking his heartworm preventative. He gives a long pause before saying “yes” while not making eye contact with you. You decide to administer a concentration test, which comes up negative, and an antibody test, which comes up positive. WTF is going?

Selecciona una de las siguientes respuestas posibles:

  • The concentration test gave a false negative because this could be an occult infection.

  • The antibody test gave a false positive and this could be allergies.

  • There are no microfilaria or worms but the antibody test came up positive because he could have received adulticide treatment less than 24 weeks ago.

  • All of the above are possibilities
