does FELV kitten imply FELV mama?

[Gloria B. Lane]

I've got a question.... I've got a feral mama cat (Fatima)  and her sweet 
little 3 month old kitten (Babycakes).  Babycakes is easy to handle.  Mama 
Fatima is not.

If we test Babycakes for FELV/FIV, will that imply the status of feral mama 
Fatima?

  So... if Babycakes is FELV+, will that mean Fatima  is FELV+?
   And if Babycakes is FELV-, will that mean Fatima is FELV-?
Just looking for an easy way to find out!  Any info is appreciated - thanks!
