Abbott Laboratories Products & Services

Abbott is diversified across healthcare rather than depending on one product line. Its main businesses include medical devices, diagnostics, nutrition, diabetes care, biowearables, and established medicines.

FreeStyle Libre

FreeStyle Libre is Abbott’s continuous glucose monitoring platform for people with diabetes. Small wearable sensors continuously measure glucose and send data to compatible readers or smartphones, helping users and clinicians make informed diabetes-management decisions.

Libre Duo

Libre Duo is Abbott’s newer glucose and ketone sensing platform. In 2026, Abbott announced U.S. authorization of Libre Duo 10 Day, which continuously monitors glucose and ketone levels through one wearable sensor.

Lingo

Lingo is Abbott’s consumer biowearable platform for adults who want to better understand glucose responses and lifestyle patterns. The system combines a wearable biosensor with a smartphone application that translates glucose patterns into personalized insights.

Ensure

Ensure is Abbott’s adult nutrition brand offering shakes and nutritional products designed to support calorie, protein, vitamin, and mineral intake. Products are commonly used by adults seeking nutritional support during aging, recovery, or periods of reduced intake.

Glucerna

Glucerna is a nutrition brand designed for people with diabetes or those managing blood-sugar-related nutritional needs. Products include shakes and other formulations developed with specialized carbohydrate and nutrient profiles.

Similac

Similac is Abbott’s infant-formula and early-life nutrition brand. The portfolio includes multiple infant-feeding formulations designed to address different nutritional, tolerance, and developmental needs.

PediaSure

PediaSure is a pediatric nutrition brand intended to help children who may need additional calories, protein, vitamins, and minerals to support growth.

Pedialyte

Pedialyte provides oral rehydration products containing electrolytes and fluids. Products are used by children and adults during dehydration caused by illness, heat, exercise, travel, or other circumstances.

Diagnostics Systems

Abbott develops laboratory diagnostic instruments and assays used in hospitals, laboratories, blood banks, clinics, and healthcare systems. Its major platforms include Alinity, ARCHITECT, Afinion, and other immunoassay, chemistry, hematology, and molecular diagnostic systems.

Point-of-Care Testing

Abbott develops portable diagnostic technologies that provide test results close to the patient rather than relying exclusively on centralized laboratories. Products such as i-STAT are used in hospitals, emergency departments, clinics, and other clinical environments.

Cancer Diagnostics

Abbott expanded into cancer screening and precision diagnostics through its acquisition of Exact Sciences in 2026. The portfolio includes Cologuard for colorectal cancer screening, Cancerguard for multi-cancer detection, Oncotype DX and molecular residual disease testing technologies.

Cardiac Rhythm Management

Abbott produces pacemakers, implantable cardiac monitors, defibrillators, electrophysiology systems, and other products used in the diagnosis and treatment of abnormal heart rhythms.

Electrophysiology

Abbott’s electrophysiology business develops mapping, ablation, and diagnostic technologies for atrial fibrillation and other cardiac-rhythm disorders. Its current pipeline includes technologies such as TactiFlex Duo.

Structural Heart

Abbott develops technologies for repairing or replacing heart valves and reducing stroke risk. Product families include MitraClip, TriClip, Amulet and other structural-heart devices.

Heart Failure Products

Abbott provides implantable and external technologies used in advanced heart-failure management, including mechanical circulatory support and remote monitoring systems.

How to Reach a Real Person at Abbott Laboratories

The correct Abbott contact depends heavily on the product involved. For FreeStyle Libre or other diabetes-care questions, call 888-332-0121. For Ensure, Similac, Pedialyte, PediaSure and other Nutrition products, call 800-986-8850. If you are unsure which business unit applies, Abbott’s general corporate email abbottcorporate@abbott.com or the main headquarters line 224-667-6100 can be used for routing, although product-specific support usually provides faster results.

Before calling, have the exact product name, lot or serial number if applicable, date of purchase or use, medical-device model, and the nature of the issue ready. For medical devices, diagnostic products, or prescription-related concerns, do not rely only on general corporate support when a specialized clinical or technical line is available.

Shareholder matters should go directly to Investor Relations at 224-667-8945 or Computershare at 888-332-2268, while job applicants can use Abbott Talent Acquisition at 877-228-4707. This separation prevents consumer-product inquiries from being routed into investor, employment, or corporate-administration channels.

How to File a Complaint Against Abbott Laboratories

Abbott complaints may involve nutrition products, diabetes devices, diagnostic systems, medical devices, customer support, billing, product quality, suspected adverse events, privacy, or shareholder matters. Because Abbott operates many separate regulated healthcare businesses, customers should first identify the exact product, business unit, lot or serial number, and whether the matter involves product quality, technical support, medical safety, or a commercial dispute.

Step 1: Contact Customer Service

Start with the Abbott business responsible for the product. Diabetes Care customers can use 888-332-0121, while Nutrition customers can use 800-986-8850. Explain the issue, provide the exact product name and identifying information, and ask for a case number. For medical-device or diagnostic issues, document any error messages, device behavior, lot numbers, and relevant dates.

Step 2: Contact the Relevant Department

If the issue involves a specialized product such as a cardiovascular implant, laboratory instrument, glucose-monitoring system, diagnostic test, or pharmaceutical product, move the complaint to the appropriate technical, clinical, quality, or medical-information department. This is particularly important when the matter could involve patient safety or device performance.

Step 3: Request Supervisor or Management Review

If the first representative cannot resolve the issue, ask for escalation to a supervisor or product-quality specialist. Provide the original case number and a concise timeline of previous contacts. For repeat product failures or disputed technical assessments, ask for review of the full case history rather than opening an unrelated new inquiry.

Step 4: Use Abbott’s Written Complaint Channel

Submit a written inquiry through Abbott’s official Contact Us process or email abbottcorporate@abbott.com when a general corporate route is appropriate. Include product details, case numbers, supporting photographs, purchase information, and previous correspondence. Written documentation is especially useful for complex complaints involving repeated technical-support interactions.

Step 5: Contact Corporate Headquarters

For serious unresolved corporate matters, write to Abbott Laboratories, 100 Abbott Park Road, Abbott Park, IL 60064-6400. Clearly identify the responsible business unit and include copies of supporting documents. The corporate office should not be used as the first step for routine product troubleshooting, but it can be appropriate for escalated administrative or legal correspondence.

Step 6: Use the Specialized Complaint or Dispute Department

Medical-device quality complaints, adverse-event reports, diagnostic product issues, privacy matters, and regulated-product concerns should follow the specialized process associated with that business. Abbott’s privacy request line for many business areas is 844-820-6570, while Diabetes Care and Nutrition maintain their own specialized contacts.

Step 7: File With the Appropriate Regulator

For regulated medical products, the appropriate external regulator may include the U.S. Food and Drug Administration. Medical-device adverse events, product-quality issues, diagnostics, nutrition, or pharmaceutical complaints can involve different FDA centers and reporting mechanisms. Customers should avoid treating every issue as the same type of regulatory complaint.

Step 8: Use Consumer Protection or Financial Dispute Options

For unresolved retail billing, delivery, subscription, or payment disputes not involving medical safety, customers may use their payment-card dispute process or the applicable state consumer-protection authority. Keep receipts, case numbers, shipment records, and Abbott responses before escalating.

Step 9: Consider Formal Legal or Arbitration Procedures

If the dispute remains unresolved and involves substantial financial loss, contractual rights, injury, or another serious claim, review the applicable product terms, warranty, medical-device documentation, or commercial agreement. Healthcare disputes can be legally complex, so independent legal advice may be appropriate before pursuing litigation or another formal dispute process.
