Abbott Laboratories Inc. ARCHITECT® STAT Troponin-I Immunoassay

Class 1 Recall
Date Recall Initiated: March 8, 2007
Product: Abbott ARCHITECT® STAT Troponin-I Immunoassay,
(List #2K41, all lots).
 
Use:

Doctors use this test in diagnosing damage to the heart and/or a heart attack (myocardial infarction) in people who have had chest pain.

A troponin I test is usually ordered, along with other cardiac tests, in the hospital to determine if a patient has had a heart attack or damage to the heart muscle. The test is conducted using a sample of the patient’s blood. The results of troponin I test should be used with additional medical tests and medical information including other cardiac markers, electrocardiogram (ECG), medical observations, and symptoms to determine if the patient has had a heart attack, or is experiencing chest pain due to other causes.

Recalling Firm: Abbott Laboratories Inc.
Firm: 100 Abbott Park Road
Abbott Park, IL 60064
Manufacturing Firm: Thermo Fisher Diagnostics
8365 Valley Pike
P.O. Box 307
Middletown, VA 22645
 
Reason for Recall:

A small number of clinical laboratories reported inconsistent or invalid test results at very low levels of troponin-I (i.e., less then 0.1ng/mL). The assay may report falsely elevated or falsely decreased results at and near this low level, which may impact patient treatment. A falsely low troponin result may cause a doctor to send a patient home with heart muscle damage or early signs of a severe heat attack which may lead to worsening of the patient’s condition, delay in treatment and potentially death. A falsely high troponin result may lead to unnecessary surgery, which carries its own risks of harm to patients.

Patients should contact their doctor if they have any concerns about their troponin-I test results.
