Asthenosphere Asthenosphere, Layer beneath the lithosphere. The asthenosphere is the layer of our planet that lies beneath the lithosphere. It was first named by J. Barrell, a British geologist when he divided the interior of the Earth into three parts. The lithosphere is the outer layer of the Earth that contains crustal plates.
It is wise, however, to have the test repeated by a different laboratory using a different technique (Western Blot). Mother cats with FIV pass antibody to their kittens whether the kittens become infected or not. So positive test results in kittens do not mean they harbor the virus of FIV. If kittens are positive, they need to be retested every two months until they are six months old to see if the test becomes negative. If the test is still positive at six month, they probably have the disease.
A few people will have a longer window period, so if you get a negative antibody test result in the first 3 months after possible exposure, you should get a repeat test after 3 months. Ninety-seven percent of people will develop antibodies in the first 3 months after they are infected.p to 1 in 12 people may test false-negative with this test. RNA tests detect the virus directly (instead of the antibodies to HIV) and thus can detect HIV at about 10 days after infectionâas soon as it appears in the bloodstream, before antibodies develop.
