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.
The age range for this test is between 6 years and 16 years 11 months. In terms of difference in scores, an individual who has taken the WISC-III, then retested with the WISC-IV may show a 5 point drop in FSIQ. This is due to new aspects of the test, and the novelty of some of the new items and subtests.
