Chart review was conducted on all hospitalized pediatric patients who underwent thyroid testing. We used a normal range of 0.5 to 5.0 \u03bcIU\/mL for thyroid-stimulating hormone (TSH) and 1.0 to 2.0 ng\/dL for free thyroxine (FT4), except for neonates for whom we used the higher reference ranges specified by the hospital laboratory.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS:<\/jats:title>\n                  <jats:p>Thyroid testing occurred in 1202 (5.7%) of 20\u2009907 hospitalizations; 79.3% had combined thyroid function tests (TFTs) with TSH + FT4 being most common, and 20.6% had TSH only. Combined TFTs were ordered routinely by psychiatry and frequently by endocrine, gastrointestinal, cardiology, and neurology services, but many cases had no identified reason for testing. Of the 205 abnormal tests (17.1%), the most common abnormalities in the combined TFTs group were normal FT4 and increased TSH (35.4%) (76% of which were between 5 and 10 \u03bcIU\/mL), normal FT4 and TSH 0.1 to 0.5 \u03bcIU\/mL (33.1%), and high FT4 but normal TSH (14.3%). Patients with new-onset type 1 diabetes had borderline low or high TSH in about 20% of cases, but all abnormalities resolved at outpatient follow-up. Overall, 8 patients (0.66%) were started on levothyroxine.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS:<\/jats:title>\n                  <jats:p>Pediatric inpatient thyroid testing is relatively common at our institution, and although results are often abnormal, they do not point to thyroid disease that has contributed to the reason for hospitalization and do not identify patients in urgent need of starting therapy.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1542\/hpeds.2018-0101","type":"journal-article","created":{"date-parts":[[2019,1,1]],"date-time":"2019-01-01T14:25:18Z","timestamp":1546352718000},"page":"24-29","source":"Crossref","is-referenced-by-count":7,"title":["Low Value of Thyroid Testing in the Pediatric Inpatient Setting"],"prefix":"10.1542","volume":"9","author":[{"given":"Ahmed","family":"Torky","sequence":"first","affiliation":[{"name":"Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, Maryland; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meredith","family":"LaRue","sequence":"additional","affiliation":[{"name":"Division of Endocrinology, Children\u2019s National Health System and School of Medicine and Health Sciences, George Washington University, Washington, DC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Kaplowitz","sequence":"additional","affiliation":[{"name":"Division of Endocrinology, Children\u2019s National Health System and School of Medicine and Health Sciences, George Washington University, Washington, DC"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"417","published-online":{"date-parts":[[2019,1,1]]},"reference":[{"issue":"5","key":"2021120817315191800_B1","doi-asserted-by":"crossref","first-page":"558","DOI":"10.1016\/0002-9343(92)90585-Y","article-title":"Admission screening by thyroid function tests in an acute general care teaching hospital","volume":"93","author":"DeGroot","year":"1992","journal-title":"Am J Med"},{"issue":"12","key":"2021120817315191800_B2","doi-asserted-by":"crossref","first-page":"1214","DOI":"10.1016\/S0025-6196(12)65408-1","article-title":"Clinical utility and cost-effectiveness of sensitive thyrotropin assays in ambulatory and hospitalized patients","volume":"63","author":"Spencer","year":"1988","journal-title":"Mayo Clin Proc"},{"key":"2021120817315191800_B3","doi-asserted-by":"crossref","first-page":"S126","DOI":"10.2337\/dc18-S012","article-title":"12.
