Above: The Fox Hole Radio built with a WWII-era âbluedâ razor blade and pencil lead for the detector. Note the bamboo coil form and the paper clip attached to a cork used to slide along the coil turns to tune the radio. The orange wire goes to the antenna, the black wire to ground.
FIV is diagnosed with a âsnapâ test, usually in combination with the Felv test. A positive FIV test almost always indicates active infection. The exception is young kittens born to an FIV positive queen. Young kittens possess antibodies to FIV from mom, but may not actually have the disease. So, if you have an FIV positive kitten, before panicking, have the kitten retested at 6 months of age.
In patients with HCV infection FibroSURE has been used to determine liver status before initiation of HCV therapy and six months after completion of therapy. It is also ordered for patients who are at increased risk of complications from a liver biopsy. In patients with HCV infection, the negative predictive value of a FibroSURE score <0.31 is 85% compared to liver biopsy and the positive predictive value of a Fibrotest score >0.48 is 61%.
