Summary: Routine Hematology provides testing for CBC and differentials, urinalysis, routine coagulation, and body fluid cell counts and differentials.

The hematology section of the Department of Pathology at the Madigan Army Medical Center performs tests in routine hematology, coagulation, urinalysis, body fluid analysis, flow cytometry, and special stains for bone marrows, body fluids, and tissue. The hematology section comprised of 8 civilian medical technologists, and 8 military medical laboratory technicians.

The mission of the hematology section is to provide quality patient care through giving accurate results of all the tests performed in the hematology section. Continuous quality improvement is a major factor in the mission of the section. Important process are monitored and evaluated for opportunities to enhance the quality and timeliness of the patient care provided. Education, through training and mentoring, is strongly emphasized to fulfill the mission of the section. The dedicated professionals in the Hematology section offer quality and competence to serve patients at Madigan Army Medical Center.

A complete range of tests is available with high-tech automated equipment and procedures in all disciplines. Some of the main tests offered by Hematology sections are the following:

o Complete Blood Count (CBC)
o Reticulocyte Count
o Manual Differential
o Body Fluid Cell Counts and Morphology
o Urinalysis with Microscopic Exam
o Prothrombin Time (PT)
o Activated Partial Thromboplastin Time (APTT)
o Mixing Studies
o Fibrinogen
o Quantitative D-Dimer
o Fibrin Split products (FSP)
o Complete Semen Analysis
o Flow Cytometry – Lymphocyte subsets and panels
o G-6-PD
o Sickle Cell
o Hgb Electrophoresis
o Factor Assays
o APCR
o Lupus Anticoagulant

The specimen containers in hematology section have lavender-top EDTA vacutainer which is properly filled and will be perfect for the CBC, ESR, and Reticulocyte count. The light blue-top sodium citrate tubes which are completely full, maximum draw will be enough for PPT, Fibrinogen, D-dimer, Fibrin split products, and mixing studies. All the tubes for the specimen must be properly filled and well-mixed to be acceptable. Dilution of blood by the appropriate anticoagulant is critical in order to get a precise result and all specimens which do not meet department standards for identification will be rejected.

Routine Hematology involves the following:

o Complete Blood Count (CBC) which consist of the following tests: WBC, RBC, HGB, MCV, MCH, MCHC, RDW, PLT, MPV, and automated differential which includes percentage and absolute number of cell types.
o A manual differential is performed only if designated laboratory criteria are met
o All peripheral smears are kept for one month
o Many tests are time dependent after collection. Routine Hematology tests that require testing in a specific time period are:
* ESR- within 8 hours of collection
* CBC- within 24 hours of collection
* Differntial- within 8 hours of collection
* PT/PTT- within 4 hours of collection
* Fibrinogen- within 4 hours of collection
* Urinalysis- within 2 hours of collection or refrigerate
