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.
Pregnancy tests have certain instructions and before you make the diagnosis of a positive pregnancy test make sure that you followed all instructions. Most manufacturers suggest to read their test after 3 minutes and to NOT READ it after 10 minutes. Once you have a negative test after 3-5 minutes THROW OUT the test. Any positive test appearing only well after that time is inaccurate and cannot be considered positive. But a false positive pregnancy test can also happen after an hCG injection like it happened to Kim Kardashian.
