More Information

Not Found

No
The document describes qualitative control materials for immunoassay tests and explicitly states "Mentions AI, DNN, or ML: Not Found".

No.
This device is a qualitative control material used in test systems to monitor reagent failure and procedural errors, not to treat or diagnose a disease in a patient.

No

Explanation: This device is described as qualitative control materials intended to monitor substantial reagent failure and procedural errors in test systems, not to diagnose a condition in a patient directly. It is an external control for immunoassays.

No

The device description clearly states it is a "qualitative control material" and mentions "reagent failure and procedural errors," indicating it is a physical control substance used in laboratory assays, not a software application.

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

Here's why:

  • Intended Use: The intended use explicitly states that the controls are "qualitative control materials intended for use in test systems to monitor substantial reagent failure and procedural errors." This indicates they are used in vitro (outside the body) to evaluate the performance of a diagnostic test.
  • Device Description: The description reinforces their use as "external controls to monitor substantial reagent failure and procedural errors in Abbott Rapid Immunoassays for the qualitative detection of Group A Streptococcal antigen." This confirms their role in the diagnostic process.
  • Performance Studies: The document describes performance studies conducted to evaluate the controls' ability to produce expected results with the associated diagnostic assays. This is typical for IVD devices.

The fact that it's a control material for a diagnostic test, rather than the diagnostic test itself, doesn't change its classification as an IVD. Control materials are essential components of many IVD systems.

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

The Relative Limit of Detection was determined by identifying the dilution levels of Strep A Stock that consistently produced low level positive results on three lots of reaction discs for each assay. Strep A Stock is a suspension of phenol-killed Strep A organisms used to make the current external Positive Control, List 03078. This suspension of phenol-killed organisms is prepared at an absorbance reading (A630) of 0.52 to 0.56.

Two lots of the Strep A Stock were used in this study. Initial dilutions of 1:10, 1:100, 1:10000 were prepared using a phosphate buffer as diluent. Both the buffer and the Strep A Stock are currently used in the manufacture of Positive Control. To determine the Relative Limit of Detection, 100 uL of the dilutions were used to seed dacron swabs. This volume simulates a swab dipped into Positive Control as required by the control package insert. The swabs were extracted for one minute and tested on three lots of reaction discs on each of the four assays. Two replicates of each dilution were assayed. The results were visually read at EOA for all assays. Additional intermediate dilutions were needed to determine the Relative Limit of Detection for TPSA and TP+SA-OBC II, 1:667 for both assays and 1:500 for TP+SA-OBC II (see Table 1).

Results:
For TPSA, the greatest dilution which consistently produced positive results was 1:667; that is, dilutions greater than 1:667 did not consistently produce positive results for the two lots of Strep A suspensions and for the three lots of TPSA used.

For TP+SA and TP+SA OBC, the greatest dilution which consistently produced positive results was 1:1000; that is, dilutions greater than 1:1000 did not consistently produce positive results for these two assays.

For TP+SA OBC II, the greatest dilution which consistently produced positive results was 1:500; that is, dilutions greater than 1:500 did not consistently produce positive results for this assay.

Summary:
These data suggest the manufacture of a "new" positive control made at approximately ten times (one log above) the relative limits of detection for the four assays . This corresponds to a 1:100 dilution of the stock Strep A suspension (refer to Table 2).

510(k) Summary Abbott STREP A Controls

Summary of Safety and Effectiveness Information Supporting a Substantial Equivalent Determination

The following information as presented in the PreMarket Notification (510(k) for Abbott STREP A Controls) constitutes data supporting a substantially equivalent determination.

Substantial equivalence has been demonstrated between Abbott STREP A Controls and Abbott STREP A Controls, K922490.

The Abbott STREP A Controls, K965252 is the same as Abbott STREP A Controls, K922490. The controls are intended for use as external controls to monitor substantial reagent failure and procedural errors in Abbott Rapid Immunoassays for the qualitative detection of Group A Streptoccal antigen . Studies were performed to demonstrate that two lots of Strep A positive control gave 100% correct results across each of the Abbott Rapid Group A Strep Immunoasays (three lots each). Four lots of Strep A negative controls were tested and gave 100% correct results across three lots of TestPack Plus Strep A with OBC.

In conclusion, these data demonstrate that the Abbott STREP A Controls is as safe and effective and is substantially equivalent to Abbott STREP A Controls, K922490.

RELATIVE LIMIT OF DETECTION OF ABBOTT RAPID STREP A ASSAYS

Purpose:

To determine the Relative Limit of Detection for the Abbott Rapid Strep A assays: TestPack Strep A (TPSA), List 01301. TestPack Plus Strep A (TP+SA). List 03A59, TestPack Plus Strep A with On Board Controls (TP+SA-OBC), List 01B53, and the upcoming TestPack Plus Strep A with On Board Controls II (TP+SA-OBC II), List 05C63.

Method:

The Relative Limit of Detection was determined by identifying the dilution levels of Strep A Stock that consistently produced low level positive results on three lots of reaction discs for each assay. Strep A Stock is a suspension of phenol-killed Strep A organisms used to make the current external Positive Control, List 03078. This suspension of phenol-killed organisms is prepared at an absorbance reading (A630) of 0.52 to 0.56.

Two lots of the Strep A Stock were used in this study. Initial dilutions of 1:10, 1:100, 1:10000 were prepared using a phosphate buffer as diluent. Both the buffer and the Strep A Stock are currently used in the manufacture of Positive Control. To determine the Relative Limit of Detection, 100 uL of the dilutions were used to seed dacron swabs. This volume simulates a swab dipped into Positive Control as required by the control package insert. The swabs were extracted for one minute and tested on three lots of reaction discs on each of the four assays. Two replicates of each dilution were assayed. The results were visually read at EOA for all assays. Additional intermediate dilutions were needed to determine the Relative Limit of Detection for TPSA and TP+SA-OBC II, 1:667 for both assays and 1:500 for TP+SA-OBC II (see Table 1).

Results:

Refer to Table 1 which shows the test results for swab samples seeded with 1:10, 1:500, 1:667, 1:1,000, 1:2000 and 1:10,000 dilutions from two lots of stock Strep A suspensions.

For TPSA, the greatest dilution which consistently produced positive results was 1:667; that is, dilutions greater than 1:667 did not consistently produce positive results for the two lots of Strep A suspensions and for the three lots of TPSA used.

For TP+SA and TP+SA OBC, the greatest dilution which consistently produced positive results was 1:1000; that is, dilutions greater than 1:1000 did not consistently produce positive results for these two assays.

For TP+SA OBC II, the greatest dilution which consistently produced positive results was 1:500; that is, dilutions greater than 1:500 did not consistently produce positive results for this assay.

Summary:

These data suggest the manufacture of a "new" positive control made at approximately ten times (one log above) the relative limits of detection for the four assays . This corresponds to a 1:100 dilution of the stock Strep A suspension (refer to Table 2).
