[QUOTE="madman, post: 228478, member: 13851"] It's coming. Time to put a nail in the coffin on this FT S**TSHOW! [I][B]*Measuring FT is technically challenging and shows high variability. [U]The CDC clinical standardization program is developing a high throughput method using the gold-standard equilibrium dialysis (ED) procedure with isotope dilution ultra-high-performance liquid chromatography-tandem mass spectrometry (ID-UHPLC-MS/MS[/U]) [I]*[U]Currently, the CDC is developing a harmonized method for free T based on calculated free T using REVISED FORMULAE[/U]. This may bring the measurement of free T to a referable standard in clinical laboratories and common reference intervals that all clinicians can use *Assays that are standardized are designed to provide accurate results,[U] traceable to “true” value-assigned certified reference materials and gold-standard reference methods[/U]. Results obtained using standardized methods can be compared across assays, institutions, populations, and past and future test results, thereby improving diagnosis, treatment, and outcomes of patients * Limitations of using free testosterone by equilibrium dialysis and calculated free testosterone concentrations in practice are the [U]lack of assay standardization, an accuracy-based quality control program, and a harmonized reference range[/U]. Until these limitations are addressed, free testosterone by equilibrium dialysis and calculated free testosterone should use reference ranges established by individual laboratories or their specific assay method[/I][/B][/I] [URL unfurl="true"]https://www.excelmale.com/forum/threads/the-importance-of-accurate-hormone-tests.23200/[/URL] [I][B]*but let me show you some additional data which persuade me that no equation can ever be an accurate measure of the free testosterone at all levels of SHBG, testosterone, estradiol, DHT, and albumin under all conditions in men and women[/B][/I] [/QUOTE]
