Intended Use
For in vitro diagnostic use in the quantitative determination of total testosterone (bound and unbound) in serum using the ADVIA Centaur and ADVIA Centaur XP systems. Measurements of testosterone are used in the diagnosis and treatment of disorders involving the male sex hormones (androgens), including primary and secondary hypogonadism, delayed or precocious puberty, impotence in males and, in females, hirsutism (excessive hair) and virilization (masculinization) due to tumors, polycystic ovaries, and adrenogenital syndromes.

More Information

No
The description details a standard immunoassay using chemiluminescent technology, with no mention of AI or ML in the device description, intended use, or performance studies.

No
This device is for in vitro diagnostic use, meaning it's used to diagnose conditions by analyzing samples outside the body. It quantifies total testosterone, which helps in the diagnosis and treatment of disorders. It is not a device that directly treats or provides therapy to a patient.

Yes

The Intended Use / Indications for Use section explicitly states "For in vitro diagnostic use in the quantitative determination of total testosterone (bound and unbound) in serum" and that these measurements "are used in the diagnosis and treatment of disorders." This directly indicates its role as a diagnostic device.

No

The device description clearly outlines physical reagents and components (Primary Reagent ReadyPack, Lite Reagent, Solid Phase, Probe Wash, Ancillary Reagent ReadyPack, Releasing Agent, Calibrators) which are hardware/consumable elements, not software. The methodology is a competitive immunoassay, which is a laboratory technique involving physical components and chemical reactions.

Yes, this device is an IVD (In Vitro Diagnostic).

The "Intended Use / Indications for Use" section explicitly states: "For in vitro diagnostic use in the quantitative determination of total testosterone (bound and unbound) in serum using the ADVIA Centaur and ADVIA Centaur XP systems."

This statement clearly indicates that the device is intended to be used outside of the body (in vitro) to diagnose or aid in the diagnosis of various medical conditions by analyzing a biological sample (serum).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

10.1 Precision

A 20-day precision study was performed according to CLSI EP5-A2. Samples included human specimen pools, three levels of controls and one in-house serum control. Each sample was assayed in 2 replicates per run, 2 runs per day for 20 days for a total of 80 replicates. Results from a representative lot are presented below.

10.2 Linearity

A linearity study was performed using the modified device according to CLSI EP06-A using 9 serially diluted samples spanning the assay range. The samples were assayed in triplicate and the mean of triplicate results was used for the analyses. As presented below, the mean recovery was between 90% and 110% and the bias from the linear fit estimate was
