We also offer state-of-the-art testing in Chemistry, Coagulation, Flow Cytometry, Hematology, Immunology, Microbiology, Molecular Diagnostics, Cytogenetics and Toxicology.

Our Services

Blood Bank / Transfusion Medicine

This department handles all activities related to the transfusion of blood and blood components. Accredited by the American Association of Blood Banks (AABB) and the College of American Pathologists (CAP), our blood bank is inspected and licensed by the Pennsylvania Department of Health (DOH) and the U.S. Food and Drug Administration (FDA).

The department supports a robust patient demographic within the Lehigh Valley, which obstetrical, neonatal, medical-surgical, oncological, pediatric, burn and trauma patients.

The Transfusion Medicine Medical Director, who is certified in Pathology and Transfusion Medicine, is trained in blood product selection and patient management, immunohematology, apheresis and coagulation; and is available as a consultant for physicians who require expert advice on these subjects. The technologists are trained in compatibility testing for the transfusion of red blood cells, plasma, platelets, cryoprecipitate and granulocytes. Medical technologists process and distribute blood products under the supervision of the medical director.

Chemistry

This department analyzes body fluids such as blood and urine for indicators of disease. Heart attacks, kidney failure, infections, diabetes, thyroid conditions and high cholesterol are a few of the most common conditions for which chemistry tests are performed. 

At Health Network Laboratories, we offer almost 2,500 comprehensive tests to measure chemistry for things such as renal function, water electrolytes, acid based balance, blood gases, metabolic intermediaries, inorganic ions, biochemical markers, carbohydrates, lipids, specific proteins, liver function, enzymology, hormones, endocrine function, toxicology and therapeutic drug monitoring.

A wide range of analytical techniques are used to perform these tests.

Coagulation

Health Network Laboratories Coagulation department offers routine and specialized coagulation testing. Our routine testing consists of screening tests for factor deficiencies as well as monitoring coumadin and heparin therapy.

Through our specialized coagulation testing we are able to aid in the diagnosis of bleeding and thrombotic disorders. We offer platelet aggregation for the evaluation of platelet function and factor assays for inherited or acquired factor deficiencies.  Thrombotic disorders can be detected with our acquired and inherited hypercoagulability profiles.

Cytogenetics

Health Network Laboratories’ cytogenetics laboratory provides physicians and patients with direct access to the most advanced chromosome analysis – an essential diagnostic testing capability for identifying genetic abnormalities. Information about genetic aberrations is useful to oncologists in cancer diagnosis, disease classification, monitoring and treatment decisions, as well as providing vital genetic information to individuals experiencing spontaneous miscarriages or infertility.

Our state-of-the-art cytogenetics laboratory utilizes both conventional karyotyping and FISH (fluorescent in situ hybridization) in order to diagnose, treat or predict risk for individuals with congenital malformations, mental retardation, multiple spontaneous miscarriages, fertility issues, products of conception and for hematological malignancies and other neoplastic processes. As the medical world moves towards personalized medicine, cytogenetics enables Health Network Laboratories to be a partner in the effort to help treat the right patient with the right drug at the right time.

Flow Cytometry

Flow cytometry is a laser-based technology that allows for cell counting, cell sorting, the detection of biomarkers and protein engineering. At Health Network Laboratories, our flow cytometry laboratory employs advanced 8-color immunophenotyping in the evaluation of peripheral blood, bone marrow, lymphoid tissue and cell-containing fluids.

Using this technology, we can identify cell surface antigens and intracellular proteins, which complements the services offered by our comprehensive anatomic pathology experts. Our reports incorporate information on multiple cell parameters, including cell surface antigens, intracellular proteins and DNA content.

The close collaboration between our board-certified hematopathologist and experienced, highly-skilled flow cytometrist helps ensure optimal quality control and accurate results.

Hematology

At Health Network Laboratories, our hematology laboratory offers a wide array of tests for the the analysis and diagnosis of disorders in leukocytes (white cells), erythrocytes (red cells) and thrombocytes (platelets) and their formation in the bone marrow (hematopoiesis).
We process full blood counts, blood films and bone marrow samples. We are available for consult on peripheral blood, bone marrow, CSF specimens and other specimens.

Molecular Diagnostics

Molecular testing is changing the way physicians diagnose and treat disease. Clinical applications can be found in infectious diseases, oncology, pharmacogenomics, genetic disease screening and coagulation. These tests help us understand diseases at the molecular and genetic levels. This can be translated to diagnostic, prognostic and therapeutic applications.

HNL’s Molecular Diagnostics Department utilizes sophisticated molecular techniques, including multiplex bioassays and real-time PCR to aid in the care of our patients.  Our laboratory offers infectious disease testing, including HIV and HCV viral load testing to assist in pharmacological patient monitoring.  Genetic testing includes prenatal CF carrier screens as well as other inherited and acquired genetic mutations.

Point-of-Care Testing (POCT)

Point-of-care testing (POCT), as defined by the College of American Pathologists (CAP), is testing performed outside the physical facilities of the clinical laboratory, in proximity to the patient on whom the testing is performed. The central feature of POCT is that it does not require permanent, dedicated space. Some common examples of POCT include urinalysis, urine pregnancy, occult blood, glucose, whole blood INR, and blood gas testing. Many of these tests can be performed on devices which communicate with a data management system which sends results to the patients’ electronic medical record, eliminating paper and ensuring regulatory compliance.

POCT is increasingly being seen as a testing modality with performance expectations similar to traditional laboratory testing and requiring the same high standards. POCT should be considered as a part of the continuum of the clinical laboratory’s contribution to healthcare and a fundamental responsibility of laboratory services. As healthcare reform changes the perspective from fee for service to the optimization of overall patient care, POCT can be a critical factor in streamlining and improving laboratory services.

Special Chemistry

The majority of the special chemistry offered by Health Network Laboratories are used to investigate less common diseases so they are not ordered as frequently as tests for more common diseases. Our special chemistry laboratory utilizes electrophoresis, HPLC, nephelometry, enzyme immunoassay and western blot methods. This testing can be performed on a wide variety of specimens including blood, urine and stool.

Subspecialty areas of focus include protein studies for multiple myeloma, hemoglobinopathy evaluations, and tumor marker testing. Allergy testing (ImmunoCAP system) is also provided by this part of our lab.
