What is the role of a Pathologist like Dr. Ostrowski in healthcare?

A Pathologist, such as Dr. Ostrowski, is a medical doctor who specializes in diagnosing diseases by examining tissues, cells, and body fluids. They analyze samples obtained from biopsies, surgeries, or autopsies under a microscope and perform laboratory tests to identify abnormalities, determine the nature of a disease (like cancer or infection), and assess its severity. Pathologists provide crucial information that guides treatment decisions made by other physicians. Dr. Ostrowski, as a Anatomical Pathologist involved in the medical specialty concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids such as blood and urine, as well as tissues., plays a vital role in patient care through accurate and timely diagnosis.

How long does it usually take to get pathology results from Dr. Ostrowski's lab?

The turnaround time for pathology results can vary depending on several factors, including the type and complexity of the specimen, the number of specialized tests required (e.g., immunohistochemistry, molecular studies), and the overall lab workload. Simple biopsies might have results in a few days, while more complex cases or those needing extensive ancillary testing might take a week or longer. Your treating physician, who ordered the tests and receives the report from Dr. Ostrowski, is the best person to provide an estimated timeframe for your specific results.

What kinds of samples does a Pathologist like Dr. Ostrowski examine?

Pathologists like Dr. Ostrowski examine a wide variety of biological samples. These include small tissue samples from biopsies (e.g., skin, colon, breast), larger surgical resections of organs or tumors, cytological preparations (like Pap smears or fluid samples from body cavities), blood smears, bone marrow aspirates and biopsies, and, in some cases, entire bodies during an autopsy. Each type of specimen provides unique information for diagnosing different diseases. As a Anatomical Pathologist involved in the medical specialty concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids such as blood and urine, as well as tissues., Dr. Ostrowski is skilled in interpreting these diverse samples.

Will I meet Dr. Ostrowski directly as a patient?
