medical reviewed by Best HGH Doctors and Clinics dedicated team. Evidence based How to test IGF-1 Normal IGF-1 levels by age How can low or high IGF-1 affect your life? What to do with IGF-1 imbalance? The insulin-like growth factor 1 (IGF-1) is the main mediator of the human growth hormone (HGH). In successfully-treated patients, both levels should be within the normal range, ideally within the lower third. . Boquete HR, Sobrado PGV, Fideleff HL, et al. Evaluation of diagnostic accuracy of insulin-like growth factor (IGF)-1 and IGF-binding protein-3 in growth hormone-deficient children and adults using ROC plot analysis. J Endocrinol . Overview Test Id : IGFMS Order This Test Insulin-Like Growth Factor-1, Mass Spectrometry, Serum Useful For Evaluation of growth disorders Evaluation of growth hormone deficiency or excess in children and adults Monitoring of recombinant human growth hormone treatment Follow-up of individuals with acromegaly and gigantism Method NameTherefore, understanding the regulation of autocrine/paracrine synthesis of IGF-1 is necessary to interpret changes in serum IGF-1 concentrations. IGF-1 exerts its effects via activation of the IGF-1 receptor . This receptor is widely distributed, which enables blood-transported IGF-1 to coordinate balanced growth among multiple tissues and organs. IGF-1 is a relatively small peptide (molecular weight 7647) that is tightly bound in serum to one of several high affinity binding proteins. 1 IGF-1 has approximately 50% sequence homology with proinsulin and has a number of biological activities similar to insulin. IGF-1 is a hormone that serves as the major effector of GH-stimulated somatic growth, as well as GH-independent anabolic . Normal ranges vary by age. For diagnosing acromegaly: If your IGF-1 is normal but your GH is low, you likely don't have acromegaly. If your IGF-1 is high and your GH is high, you may have acromegaly. Levels of IGF-1 that are higher or lower than normal may also be caused by: Hypothyroidism, or low thyroid hormone levelsThe ideal level for IGF-1 should be 300-350 mcg/ml (slightly higher in females). Normally this is the value for 20-25 year olds. Depending on your lifestyle and diet this ideal level may vary widely. Generally the normal values drop about 10% per decade. Low IGF-1 is considered by most to be between 84-100 µ/l and numerous studies recommend that raising IGF-1 to high normal range reverses Chronic Medical Diseases (CMD), improves bone mineral density (BMD), and fibromyalgia. In successfully-treated patients, both levels should be within the normal range, ideally within the lower third. . Fideleff HL, et al. Evaluation of diagnostic accuracy of insulin-like growth factor (IGF)-1 and IGF-binding protein-3 in growth hormone-deficient children and adults using ROC plot analysis. J Endocrinol Metab. 2003;88:4702-4708 . Normative data included the range of values (2. 5-97. 5 percentiles) given by the six IGF-I assays according to age group and sex. A formula for SDS calculation is provided. Although the lower limits of the reference intervals of the six assays were similar, the upper limits varied markedly. Pairwise concordances were moderate to good (0. 38-0. 70). The diagnosis of growth hormone deficiency (GHD) in childhood and adolescence is based on auxological, biochemical, neuro-radiological, and genetic investigations. Since GH production is pulsatile, its secretion needs to be assessed by provocative tests. Random growth hormone (GH) levels in a healthy person range as follows: Men: < 5 ng/mL or < 226 pmol/L Women: < 10 ng/mL or < 452 pmol/L Children: 0-20 ng/mL or 0-904 pmol/L Newborns: 5-40. GHD was defined as peak GH ≤ 6. 0 ng/mL in the two tests. We identified 60 and 238 patients with and without GHD, respectively. The mean IGF-1 standard deviation (SD) was not significantly. GH deficiency. In children, GH is essential for normal growth and development. A GH deficiency can cause a child to grow more slowly and be much shorter than children of the same age. In adults, GH deficiency can lead to low bone density and reduced muscle mass. GH insensitivity, also known as Laron syndrome. Persons with anorexia or malnutrition often have low IGF-1 concentrations. Reference ranges in pregnancy have not been formally established. . IGF-1 concentrations increase approximately 2-fold during normal uterine pregnancy compared to pre-pregnancy baseline. . (IGF)-1 and IGF-binding protein-3 in growth hormone- deficient children and . [8] IGF-1 is produced primarily by the liver. Production is stimulated by growth hormone (GH). Most of IGF-1 is bound to one of 6 binding proteins (IGF-BP). IGFBP-1 is regulated by insulin. IGF-1 is produced throughout life; the highest rates of IGF-1 production occur during the pubertal growth spurt. [9]This variability is presumed to be much less than the normal range of variation of IGF-1 in cow's milk due to natural factors, but more research is needed. IGF-1 in milk is not denatured (inactivated) by pasteurization. . Insulin-like growth factor-I, its binding proteins (IGFBP-1 and IGFBP-3), and growth hormone and breast cancer risk in the . Δ For monitoring rhGH therapy, target range for IGF-1 is the upper one-half of the normal range (ie, IGF-1 0 to +2 SD). IGF-1 levels below this target range are associated with subnormal growth response to therapy; IGF-1 levels above this target range (ie, >+2 SD) may be associated with possible adverse effects of rhGH. . growth hormone; IGF . IGF-1 (insulin-like growth factor - 1) is released in response to growth hormone and remains stable in the bloodstream longer it is the test normally used for checking HGH in adults. Blood Tests to Check HGH and Diagnose GH Deficiency IGF-1 Levels (Somatomedin C) - BLOOD Reference Range - pg/ml - Reference Range - pg/ml - Reference Range - pg/ml -Print with all Pictures. Short for insulin-like growth factor 1, IGF-1 is a hormone that helps control the growth and development of organs, muscles, and tissues in the body. IGF-1 also has a hand in controlling glucose metabolism and brain function. Originally called somatomedin C, IGF-1 is synthesized mainly by the liver but is also produced . What is this test? 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 manage the effects of growth hormone (GH) in your body. Normal IGF-1 and GH functions include tissue and bone growth. Growth hormone tests measure the amount of growth hormone in your blood. . you'll also have higher- or lower-than-normal levels of IGF-1. . The range for normal results may vary depending on . The postnatal growth rate of patients with LS is very slow, the distance from the lowest normal centile increasing progressively. If untreated, the final height is 100-136 cm for female and 109-138 cm for male patients. . Conclusion—IGF-1 is an important growth hormone, mediating the protein anabolic and linear growth promoting effect . Normal concentrations of Insulin-like growth factor-1 (IGF-1) must be considered in context. Some patients can have a growth hormone (GH) deficiency and still have a normal IGF-1 concentration. Decreased IGF-1 If IGF-1 concentrations are decreased, then it is likely that there is GH deficiency or an insensitivity to GH.
