This test is intended for use in clinical laboratories or physician office laboratories. For in vitro diagnostic use only.
Device Description
The S-Test albumin (ALB) reagent cartridge used with the S40 Clinical Analyzer is intended for quantitative in vitro diagnostic determination of ALB in serum or heparin plasma based on a photometric test measuring the formation of a bluish-green complex from ALB and bromcresol green.
More Information

Not Found

No
The summary describes a photometric chemical assay for albumin and does not mention any AI or ML components.

No

The device is an in vitro diagnostic reagent used for the quantitative determination of albumin, which aids in diagnosis and treatment, but it does not directly provide therapy or treatment.

Yes

This device is intended for the quantitative determination of albumin concentration in serum or heparin plasma, and these measurements are used in the diagnosis and treatment of various diseases primarily involving the liver or kidneys. The "Intended Use" explicitly states "For in vitro diagnostic use only."

No

The device is a reagent cartridge used with a clinical analyzer, which are physical components and not solely software.

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

Here's why:

  • Intended Use/Indications for Use: Explicitly states "For in vitro diagnostic use only." It also describes the intended use as the "quantitative determination of albumin concentration in serum or heparin plasma," which is a diagnostic measurement performed outside of the body.
  • Device Description: Describes the device as an "in vitro diagnostic determination of ALB in serum or heparin plasma."
  • Intended User/Care Setting: Specifies use in "clinical laboratories or physician office laboratories," which are typical settings for in vitro diagnostic testing.

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

Performance data on the S-Test ALB included precision, accuracy, and sensitivity data.
Precision: In testing conducted at three ALB levels for 22 days, the within-run CV ranged from 1.8 to 2.0%, and total CV ranged from 4.7 to 5.6%. In precision studies at three separate Physician Office Laboratory (POL) sites and in-house over five days, the within-run CVs ranged from 0.6 to 2.5% and total CVs ranged from 0.8 to 2.8%.
Accuracy: In the correlation study, 92 samples with ALB values ranging from 0.7 to 6.8 g/dL were assayed on the S40 Clinical Analyzer using S-Test ALB (y) and a comparative method (x). Least-squares regression analysis yielded a correlation coefficient of 0.961, a standard error estimate of 0.24 a confidence interval slope of 0.873 to 0.982, and a confidence interval intercept of 0.05 to 0.51. In patient correlation studies at four separate POL sites using the S40 Clinical Analyzer and a comparative method, least-squares regression analysis yielded correlation coefficients ranged from 0.987 to 0.994, standard error estimates of 0.12 to 0.19, confidence interval slopes of 0.942 to 1.040, and a confidence interval intercept of -0.27 to 0.09.
Sensitivity: The detection limit was 0.4 g/dL.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

Precision (CV: 0.6-2.5% within-run, 0.8-2.8% total), Accuracy (correlation coefficient: 0.961, 0.987-0.994), Sensitivity (detection limit: 0.4 g/dL).
