## Indications for Use

The HEMOCHRON® Electronic System Verification Tube is intended for in vitro diagnostic use in performing a quantitative electronic detection system verification of HEMOCHRON® Coagulation Instruments. The Electronic System Verification Tube electronically simulates test initiation and clot detection in the same manner as patient assay end points are recorded.

## Device Story

The HEMOCHRON® Electronic System Verification Tube (ESVT) is a plastic tube containing battery-operated electronic circuitry used for quality control of HEMOCHRON® coagulation instruments. It simulates test initiation and clot detection at 100, 300, and 500-second intervals. The device is inserted into the instrument's test well; the instrument measures the simulated clotting time, which is then compared against the ESVT's known values to verify the functionality of the test well and detector. This process ensures the instrument's timing capability and well rotation are operating correctly. It is used in clinical settings by healthcare personnel to perform routine quality control checks, ensuring the accuracy of patient coagulation assays.

## Clinical Evidence

Bench testing only. Precision was validated using three different operators on HEMOCHRON® models 401, 801, 8000, and Response over a minimum of three days. Results for 120 samples per level: Normal (90-110s) mean 97.56s (CV 2.74%); Abnormal I (290-310s) mean 297.3s (CV 1.02%); Abnormal II (490-510s) mean 497.6s (CV 0.63%).

## Technological Characteristics

Plastic tube housing battery-operated electronic circuitry. Simulates clotting time via electronic signal generation. Dimensions/form factor: tube-shaped for insertion into instrument test well. Standalone operation. No software algorithm class specified; device functions via integrated electronic timing circuits.

## Regulatory Identification

A multipurpose system for in vitro coagulation studies is a device consisting of one automated or semiautomated instrument and its associated reagents and controls. The system is used to perform a series of coagulation studies and coagulation factor assays.

## Special Controls

*Classification.* Class II (special controls). A control intended for use with a multipurpose system for in vitro coagulation studies is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 864.9.

## Predicate Devices

- HEMOCHRON® Verify System / Factor VI Qualify System ([K940957](/device/K940957.md)/S1)

This summary of safety and effectiveness is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.

#### Device Name

| Common / Usual Name: | HEMOCHRON® Electronic Quality Control (EQC)           |
|----------------------|-------------------------------------------------------|
| Product Name:        | HEMOCHRON® Electronic System Verification Tube (ESVT) |

#### Predicate Device

HEMOCHRON® Verify System / Factor VI Qualify System (K940957/S1)

### Device Description

The Electronic System Verification Tube (ESVT) performs Electronic Quality Control on all marketed HEMOCHRON® tube instruments HEMOCHRON® models 8000, 401, 801 and the new HEMOCHRON® RESPONSE (K983475) currently under FDA review.

The device is a plastic tube with battery operated electronic circuitry that electronically simulate test initiation and clot detection using the same principles employed in a clotting time assay. Once started and placed in the Hemochron test well, the ESVT electronically simulates the operation of a 100, 300 and 500 second clotting time.

The comparison of the displayed Hemochron clotting time with the ESVT clotting time is a quality control test of the functionality of the test well and test detector.

{1}------------------------------------------------

#### Statement of Intended Use

The HEMOCHRON® Electronic System Verification Tube is intended for in vitro diagnostic use in performing a quantitative electronic detection system verification of HEMOCHRON® Coagulation Instruments. The Electronic System Verification Tube electronically simulates test initiation and clot detection in the same manner as patient assay end points are recorded.

# Summary of Technological Characteristics and Performance Data

The HEMOCHRON® ESVT is an improvement to the Electronic Quality Control designed to perform the same three (3) testing time ranges as the predicate three (3) separate electronic verification tubes. The upgrade provides the end user with additional quality features to assure the HEMOCHRON® instrument is operating properly. The ESVT is designed to check the timing capability of the HEMOCHRON instrument, as well as, verifying well rotation.

The previously approved test ranges are established in (K940957/S1).

### Specifications

| Control           | Acceptable range |
|-------------------|------------------|
| Normal level      | 90-110 seconds   |
| Abnormal level I  | 290-310 seconds  |
| Abnormal Level II | 490-510 seconds  |

Precision was validated using three different operators on all HEMOCHRON® models (401, 801, 8000, Response) over a minimum of three days. The precision study data are summarized below.

| Normal |       | Abnormal 1 |       | Abnormal 2 |       |
