Because transplant candidates require a GFR &lt;20 mL/ min/1.73m2 (1) and because the patient's malecalculated eGFR was above the cutoff, he was not listed. [...]because creatinine-based eGFR equations are dependent on sex/gender congruence and racial demographics, gender nonconformity and mixed ancestry challenge their applicability.

[...]studies on cisgender men show that decreasing testosterone concentration portends worse CKD outcomes (6, 7). What other laboratory results may be difficult to interpret in transgender patients? POINTS TO REMEMBER * A transgender individual is a person whose biological sex does not match their gender identity. * Kidney health is evaluated using laboratory measurements to estimate function (GFR) and damage (proteinuria). * Interpreting sex-specific reference limits in transgender individuals is complicated, particularly for eGFR where muscle mass is an integral component. * When assessing renal function in transgender patients, consideration should be given to sex-independent methods such as iothalamate clearance. * Address correspondence to this author at:</description><identifier>ISSN: 0009-9147</identifier><identifier>EISSN: 1530-8561</identifier><identifier>DOI: 10.1373/clinchem.2016.268839</identifier><identifier>PMID: 29089320</identifier><language>eng</language><publisher>United States: Oxford University Press</publisher><subject>Adult ; Creatinine ; Damage assessment ; Demographics ; Diet ; Endocrine therapy ; Evaluation ; Female ; Gender ; Gender aspects ; Gender identity ; Glomerular Filtration Rate ; Humans ; Kidney diseases ; Kidney Transplantation ; Kidney transplants ; Kidneys ; Laboratories ; Male ; Men ; Mens health ; Muscles ; Patients ; Proteins ; Proteinuria ; Renal function ; Renal Insufficiency, Chronic - diagnosis ; Renal Insufficiency, Chronic - surgery ; Sex ; Testosterone ; Transgender Persons ; Transplants &amp; implants ; Urine ; Womens health</subject><ispartof>Clinical chemistry (Baltimore, Md.), 2017-11, Vol.63 (11), p.1680-1683</ispartof><rights>Copyright American Association for Clinical Chemistry Nov 2017</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c335t-f7a19636fb1761b38a1d56322ab328bc40fe02afa93bde60b9ed109ca7ef3eaf3</citedby><cites>FETCH-LOGICAL-c335t-f7a19636fb1761b38a1d56322ab328bc40fe02afa93bde60b9ed109ca7ef3eaf3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27901,27902</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/29089320$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Whitley, Cameron T</creatorcontrib><creatorcontrib>Greene, Dina N</creatorcontrib><title>Transgender Man Being Evaluated for a Kidney Transplant</title><title>Clinical chemistry (Baltimore, Md.)</title><addtitle>Clin Chem</addtitle><description>Urine protein excretion was 3 g/day.
