Insulin-like growth factor binding protein 3 (IGFBP-3) is the main carrier of somatomedin C (also called insulin-like growth factor-1, or IGF-1) in the body. Blood levels of both these proteins are controlled by human growth hormone (hGH), a hormone that’s produced by the pituitary gland, a pea-sized gland in the brain that works with the endocrine system. The pituitary gland regulates growth and the function of other glands.
But IGFBP-3 is more than just a transporter. It also helps extend the life of somatomedin C in the blood and helps control its effects on body tissues.
Levels of IGFBP-3 are highest during childhood and puberty, then they decrease during adulthood. Levels also may be affected by sexual maturation and nutritional status
A vision screening, also called an eye test, is a brief exam that looks for potential vision problems and eye disorders. Vision screenings are often done by primary care providers as part of a child’s regular checkup. Sometimes screenings are given to children by school nurses.
Vision screening is not used to diagnose vision problems. If a problem is found on a vision screening, your or your child’s provider will refer you to an eye care specialist for diagnosis and treatment. This specialist will do a more thorough eye test. Many vision problems and disorders can be successfully treated with corrective lenses, minor surgery, or other therapies.
This test measures the amount of dihydrotestosterone in the blood. DHT is a hormone derived from testosterone and is directly linked to male and female baldness, sexual development in puberty, acne, and prostate enlargement / cancer.
A D-dimer test looks for D-dimer in blood. D-dimer is a protein fragment (small piece) that’s made when a blood clot dissolves in your body.
Blood clotting is an important process that prevents you from losing too much blood when you are injured. Normally, your body will dissolve the clot once your injury has healed. With a blood clotting disorder, clots can form when you don’t have an obvious injury or don’t dissolve when they should. These conditions can be very serious and even life-threatening. A D-dimer test can show if you have one of these conditions.
Medical tests can help detect a condition, determine a diagnosis, plan treatment, check to see if treatment is working, or monitor the condition over time. A doctor may order these tests as part of a routine checkup, to check for certain diseases and disorders, or to monitor your health.
