Access to scientific, accurate, appropriate, and safe diagnostics, and reliable laboratory services is paramount for diagnosis and disease management, surveillance, and securing safe investigations. However, testing results are only of value to those making clinical decisions, if the test results reported are timely and correct. Selection and procurement of diagnostics and laboratory technologies is often challenging given the wide choice of products and suppliers in the global market. Understanding of the needs at each level of the health system is critical and should be the first step.
You need to understand your geographic location, demands and medical facility and specialty, and super-specialty work available surrounding your workplace. Clear technical specifications and good procurement practices are necessary to guide sound procurement decisions. This is especially important to ensure that appropriate and safe diagnostics of good quality are placed in health facilities according to the needs. Service-delivery systems may need to be adapted
to ensure that access to diagnostics is equitable, meaning access to testing services can reach all of those in need.
Unlike pharmaceutical products, methods for selection and procurement of diagnostics have to be tailored to the end user; hence, procedures may differ between the types of diagnostics. In particular, the desired testing throughput, staff competencies and training requirements, storage, stability of utilities, cold chain, test through-put, local service and technical support, quality-assurance measures, and site infrastructure will greatly impact the choice of diagnostics in a particular health facility.
A combination of factors, at the facility level and at the national level, need to be considered when selecting diagnostics. In addition to national policies and guidelines, financial and regulatory factors may impact national capacity to select and manage particular types of diagnostics. We believe in saving our environment by disposing of used containers and equipment given that they are following environmental, health, and safety guidelines. Buying items made from recycled materials keeps the cycle going. Plus, recycled materials are generally less expensive.
Disease patterns that are seasonal, national, or regional may dictate the required scope of services and throughputs in specific locales.
Inspection of bone marrow is considered one of the most valuable diagnostic tools for evaluating hematologic disorders. Indications have included diagnosis, staging, and therapeutic monitoring for lymphoproliferative disorders, such as chronic lymphocytic leukemia (CLL), Hodgkin and non-Hodgkin lymphoma, hairy cell leukemia, myeloproliferative disorders, myelodysplatic syndrome, and multiple myeloma. FISH is a rapid, sensitive targeted technique that bridges the gap between cytogenetics and molecular biology.
FISH is complementary to classical karyotyping and is used as an indispensable tool for identification of recurrent genetic abnormalities, such as translocations, deletions, duplications, inversions, and amplifications at molecular level in hematological malignancies as well as solid tumors.
CISH, PCR, real-time PCR, Sanger sequencing, multiple ligation-dependent probe amplification (MLPA), NGS, microarray, and droplet digital PCR (ddPCR) are a few areas of our future investment techniques to make molecular diagnosis easily accessible.
