No
The device description and intended use clearly define it as an assayed quality control material for linearity and range verification of tumor markers, with no mention of AI or ML capabilities. The performance studies focus on stability, which is typical for control materials, not algorithmic performance.
No
The device is described as an "in-vitro diagnostic device" and an "assayed quality control material" used to simulate human patient samples for determining linearity and calibration of tumor markers, which indicates it's for diagnostic quality control, not direct therapy.
No
Explanation: This device is described as an "assayed quality control material" and an "in-vitro diagnostic device" intended to simulate human patient samples for use in determining linearity, calibration, and the verification of reportable range for analytes. It is used to ensure the accuracy of other diagnostic tests, rather than directly diagnosing a condition itself.
No
The device description clearly states it is an in-vitro diagnostic device consisting of liquid materials (human and bovine serum with analytes and additives), which are physical components, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
The document explicitly states:
- "The Linearity FD Tumor Markers II is for In Vitro Diagnostic use only." in the Intended Use section.
- "The Audit® MicroControls™ Linearity FD Tumor Markers II product is an in-vitro diagnostic device..." in the Device Description section.
These statements clearly indicate that the device is intended for use in vitro (outside of the body) for diagnostic purposes.

Device Description
The Audit® MicroControls™ Linearity FD Tumor Markers II product is an in-vitro diagnostic device consisting of two sets of five levels of liquid, linearity/QC material. Set 1 contains the analytes: Alpha fetoprotein (AFP), Carcinoembryonic antigen (CEA), Prostate-specific antigentotal (PSA), Carbonic Anhydrase-125 (CA-125), Carbonic Anhydrase 19-9 (CA19-9), and Carbonic Anhydrase 27-29 (CA27-29) (BR) and additives in human serum. Set 2 contains the analytes: free-PSA (fPSA), and Carbonic Anhydrase 15-3 (CA15-3) and additives in human serum and bovine serum. For each set there are five levels labeled A, B, C, D and E. Both sets contain 1ml for each level. Materials of human origin used in the manufacture of this linearity set have been tested using FDA approved methods and are found to be non-reactive for HbsAg and antibodies to HCV and HIV-1/2.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Stability studies have been performed to determine the reconstituted vial stability and shelf life for the Audit® MicroControls™ Linearity FD Tumor Markers II.
Shelf Life-Accelerated Stability:
Accelerated stability studies were conducted to establish the shelf life stability claims. All supporting data is retained on file at Aalto Scientific, Ltd. Acceptance criteria were met to support the product claims as follows:
Shelf Life: 2 years, when stored unopened at 2-8°C.
Shelf Life-Real Time Stability:
Vials from two lots of finished product are stored at 2-8℃ (real time vials) and -80℃ (Dayl vials). Samples are taken at two different time points. The analyte values from the real time vials are compared to the Day0 vials (both tested in duplicate). The product is determined to meet its predicted shelf life if the % difference of the real time mean values compared to the Day0 mean value is within the acceptance criteria. All supporting data is retained on file at Aalto Scientific, Ltd.
Note: Real time studies are ongoing to support the shelf life of this product.
Reconstituted Vial-Accelerated Stability+Real Time Stability:
Real time stability studies were conducted at the end of accelerated stability studies to establish the reconstituted vial stability claims. All supporting data is retained on file at Aalto Scientific, Ltd. Acceptance criteria were met to support the product claims as follows:
Reconstituted Stability: Once a vial has been opened and reconstituted, the product will be stable for 14 days when stored tightly capped at 2-8° C.

G. Value Assignment/Linearity
Analyte value assignment for Level A through Level E was performed on Siemens Advia Centaur for the analytes: AFP, CEA, PSA, CA125, CA27-29 (BR), and CA15-3 using the corresponding reagent. Analyte value assignment for the analytes: CA19-9. and free-PSA were performed on Abbott Architect i1000SR using the corresponding reagent. Each analyte was measured multiple times. The mean value of each analyte was used to establish target concentration value at each level. All supporting data is retained on file at Aalto Scientific, Ltd.
