What Does a Hematologist Do? Conditions They Diagnose and Treat

February 27, 2026, 9:23 AM
At Whitman Hematology and Infusion Therapy in Plattsburgh, NY, Todd Whitman, MD, provides specialized care for patients with a wide range of blood-related conditions. Hematology focuses on the diagnosis, treatment, and management of disorders affecting the blood, bone marrow, and lymphatic system. Understanding the role of a hematologist can help patients know when to seek expert evaluation and what to expect from their care.

Understanding the Role of a Hematologist

A hematologist is a physician trained to evaluate abnormalities in blood cells and related systems. This includes red blood cells, white blood cells, platelets, and plasma. Because these components play essential roles in oxygen transport, immune function, and clotting, even small changes can affect overall health.
Todd Whitman, MD works closely with patients to identify underlying causes of symptoms, interpret laboratory results, and develop personalized treatment plans. Hematologic care often involves detailed testing, ongoing monitoring, and coordination with other healthcare providers when needed.

Conditions a Hematologist Diagnoses

Hematologists evaluate a variety of conditions, ranging from common disorders to more complex diseases. One of the most frequently treated conditions is anemia, which occurs when there are not enough healthy red blood cells to carry oxygen throughout the body. Patients with anemia may experience fatigue, weakness, or shortness of breath.
Bleeding and clotting disorders are also a major focus. Conditions such as thrombocytopenia, which involves low platelet counts, can lead to easy bruising or prolonged bleeding. On the other hand, clotting disorders may increase the risk of abnormal blood clots that can affect circulation.
Hematologists also evaluate abnormalities in white blood cells, which can impact the immune system. While some conditions are benign and manageable, others may require more advanced care and monitoring.

How Hematologic Conditions Are Evaluated

Diagnosis begins with a thorough review of symptoms, medical history, and laboratory results. Blood tests are often the first step, providing detailed information about cell counts and function. In some cases, additional testing such as imaging or bone marrow evaluation may be recommended to better understand the condition.
At Whitman Hematology and Infusion Therapy, care is guided by careful analysis and a patient-centered approach. Each evaluation is tailored to the individual, ensuring that findings are interpreted accurately and that treatment decisions are well-informed.

Treatment and Ongoing Management

Treatment depends on the specific diagnosis and severity of the condition. Some patients benefit from nutritional support or medication to correct deficiencies, while others may require infusion therapies or more specialized interventions. Regular follow-up is often an important part of care, allowing for adjustments based on how the condition responds over time.
Todd Whitman, MD focuses on creating individualized treatment plans that address both immediate concerns and long-term health. This approach helps patients manage their condition effectively while maintaining quality of life.
