There are several species of tapeworms, and each uses a different intermediate host to infect a pet. Fleas, small rodents, rabbits or larger animals such as deer and sheep are the hosts that transmit the worms to dogs or cats. Pets infected with tapeworms do not normally lose weight or display symptoms of illness.
The Glut1 protein is also found in red blood cells (erythrocytes). Testing is available on a clinical basis to assess erythrocyte glucose transporter activity, which is reduced by approximately 50 percent in individuals with Glut1 deficiency syndrome.
IGF, IGF-1. This test measures the amount of insulin-like growth factor-1 (IGF-1) in your blood. IGF-1 is a hormone found naturally in your blood. Its main job is to regulate the effects of growth hormone (GH) in your body. Normal IGF-1 and GH functions include tissue and bone growth. IGF-1 is formed in different tissues as a result of GH in the blood. Some disorders and diseases, such as pituitary tumors, can cause your body to make too much GH. Because IGF-1 measurements relate to GH measurements, this test is used to diagnose many problems linked to too much or too little GH.
