Chemistry
The Chemistry section is a large area of the Clinical Laboratory which houses both the High Volume and the Special Chemistry testing areas. The diagnostic testing performed in this section is a mix of highly automated assays and more specialized manually performed tests. A recent addition to the department is the Vitros Automation Solutions System which includes automated sample handling modules and a rack delivery system, both which increase efficiency and improve area turn around times.
The High Volume area operates 24-7 and analyzes hundreds of samples per day. Assays include:
- Complete metabolic panels
- Thyroid assays
- Lipid panels
- Liver panels
- Cardiac markers
- Arterial and venous blood gas measurements
- Fluid osmolality
- Urinalysis
- Urine drugs of abuse screening
The Special Chemistry area operates Mon-Fri, 8 am-430 pm, with the exception of a few assays which are available via STAT requests. The testing mix in this area includes:
- Hepatitis and HIV(4th generation) screening, Hepatitis C by PCR, HIV Quantitation by PCR

State of the art tests performed enhance diagnostic capabilities for congenital and aquired bleeding disorders, hyper coagulable evaluations, platelet disorders, and autoimmune coagulation disorders. The services provided by our laboratory support the Thrombosis and Hemostasis Program and our Hemophilia Treatment Center.
- Routine coagulation including Protime, PTT, Fibrinogen, D-Dimer, and Mixing Studies
- Therapeutic monitoring for low molecular weight and unfractionated heparin
- Advanced coagulation testing including: coagulation factors, von Willebrand factor antigen and activity and thrombin time

Cytogenetics
Cytogenetics is the study of human chromosomes. Chromosome analysis provides an overview of the genome and the ability to identify chromosome rearrangements and numeric abnormalities. Karyotyping is essential in diagnosis and classification of both constitutional disorders and many malignancies. Chromosome analysis and fluorescence in situ hybridization (FISH) analysis are available for peripheral or cord blood, bone marrow, solid tumors, lymph nodes, fine needle aspirates and fetal tissue (products of conception, fascia).
The Cytogenetics Laboratory is open Monday - Friday 8:00 am - 4:30 pm and Saturday 8:00 am - 12:00 pm.
Fish
- Fluorescence in situ hybridization for a variety of constitutional and neoplastic conditions
Peripheral Blood Analysis
- Evaluation of a couple with recurrent miscarriage or infertility
- Evaluation of parents of an offspring with a chromosome abnormality
- Evaluation of a child with suspected aneuploidy, such as Turner Syndrome and Klinefelter Syndrome
Cancer Analysis
- Evaluation of Lymphomas, Leukemia, and other hematologic disorders
- Evaluation of solid tumors, especially sarcomas, renal cell carcinomas, and lipomas
Products of Conception/Stillbirth Analysis
- Recurrent Miscarriage
- Fetal death

Flow Cytometry
Flow Cytometry allows for the simultaneous multiparametric analysis for the qualitative measurement of the biological and physical properties of cells. Our section performs test such as Lymphocyte Subset Analysis (T-cell, B-cell, and NK subsets) which may be used as aids to evaluate the immune competency underlying known or unknown disease states and to monitor lymphocyte levels following organ transplantation. We also perform a test to monitor CD20 depletion in Rituximab therapy. Flow Cytometry also performs leukemia and lymphoma immunophenotyping to aid in the diagnosis of hematologic malignancy. CD34 Stem Cell Enumeration is also performed on peripheral blood and apheresis samples in the setting of stem cell transplantation.

Immunology
The Immunology Laboratory performs tests that aid in the diagnosis of autoimmune and infectious disease. Methodologies utilized include enzyme-linked immunosorbent assays (ELISA) and indirect immunofluorescence Assays (IFA). We are a fully automated and integrated Immunology Laboratory. For IFA we utilize the QUANTA-Lyser automated IFA analyzer platform, the NOVA View automated digital IFA microscope, and the QUANTA Link software which provides full traceability of patient samples from processing through reporting and significantly reduces hands-on time and improves workflow efficiencies. For ELISA we utilize the DSX which is a high-performance walk-away ELISA processing system.
