New Diagnostic Test Offerings: Serum Beta-Hydroxybutyrate Assay s of February 1, The Methodist Hospital Core Laboratory replaced the semi-quantitative serum acetone test with a quantitative enzymatic serum beta-hydroxybutyrate assay. Due to a national shortage of reagents, the acetone test will no longer be performed. Please order the betahydroxybutyrate (synonyms Ketone and Serum Ketone) for diagnosing or monitoring diabetic ketoacidosis.

Beta-hydroxybutyrate is the most abundant ketone body in the blood; acetoacetic acid and acetone are produced in

A

smaller amounts. Please note that the old nitroprusside dipstick method does not react with beta-hydroxybutyrate, therefore, the results of the acetone test do not always correlate with the results of the beta-hydroxybutyrate assay. Normal beta -hydroxybutyrate levels are ≤0.3 mmol/L and are typically >2.0 mmol/L in patients with ketoacidosis. The betahydroxybutyrate test is available 24/7.

If you have any questions or concerns, please call Dr. Ping Wang at 713-4413294 or Toni Emmott at 713-441-1861. 

H

ematopathology is the subspecialty of pathology that studies the diseases of hematopoietic cells. These diseases can be hereditary (bone marrow failure syndromes, primary immune deficiency syndromes) or acquired (nutritional deficiencies, infections, cancers). The Department of Pathology and Genomic Medicine has a team of four board-certified hematopathologists with a combined 94 years of professional training and experience

Arthur W. Zieske, M.D. Co-Medical Director, Hematopathology Dr. Zieske received his medical degree from the Louisiana State University Health Science Center (LSU-HSC) in New Orleans, where he also completed his pathology residency. He received his hematopathology fellowship training at the Yale University School of Medicine in New Haven, CT. Training the next generation of pathologists is one of Dr. Zieske’s key interests; he received several teaching awards while on the faculty at LSU-HSC. For more information on Dr. Zieske, visit methodisthealth.com/Zieske.

in hematopathology.

The team brings this extensive expertise to all facets of the hematopathology patient service that encompasses superior clinical care, education, and ground-breaking translational research.

The hematopathology team: from left, Drs. Arthur Zieske, April Ewton, Abdus Saleem, and Youli Zu.

Youli Zu, M.D., Ph.D. Co-Medical Director, Hematopathology Dr. Zu received his medical degree from the Jilin Medical College of Beihua University in Jilin City, China, and his Ph.D. in Immunology and Pathology from the Kyoto University School of Medicine in Kyoto, Japan. He completed his pathology residency at New York University Medical Center and a hematopathology fellowship at the National Cancer Institute in Bethesda.

In addition to providing clinical

services, Dr. Zu is the director of the Cancer Pathology Laboratory at The Methodist Hospital Research Institute. His research focuses on the development of novel diagnostics and treatments for hematopoietic and lymphoid disorders. His current studies, funded by the National Cancer Institute, involve development of an aptamer probe nanocomplex to diagnose and administer targeted treatment for anaplastic large cell lymphoma.

For more information on Dr. Zu, visit methodisthealth.com/Zu.

Abdus Saleem, M.D. Associate Medical Director, Hematopathology Dr. Saleem received his medical degree from the King Edward Medical School in Karachi, Pakistan. Having obtained his original subspecialty certification in 1977, he is the most experienced member of the Hematopathology Team. He has trained numerous local hematopathologists, including Dr. Jacquelin O’Hare, Dr. Munir Shahjahan, Dr. Choladda Curry, Dr. Randall Olsen, Dr. Thu Ngo, and Dr. Christine Finch. Dr. Saleem enjoys his role as the primary educator of residents and fellows in bone marrow and peripheral blood pathology.

For more information on Dr. Saleem, visit methodisthealth.com/Saleem.

April A. Ewton, M.D. Associate Medical Director, Hematopathology Dr. Ewton obtained her medical degree and completed her residency training at the Baylor College of Medicine. She received her hematopathology fellowship training at the University of New Mexico in Albuquerque. As associate director of clinical pathology resident training, Dr. Ewton is especially involved with hematopathology education.

“I just love working with Drs. Awalt and Piao and the rest of the laboratory.

We all work well together and really keep things moving along.”

Tracie J. Koen, M.D.

“The Willowbrook laboratory is ideal because we get to see interesting cases, in a smaller, community setting. It’s the best of both worlds.”

Yingchao Piao, M.D., Ph.D.

“It is very exciting to watch the response of the laboratory team to the challenges that new service lines bring.

The team never disappoints.”

Anita G. Farr, M.H.A.
