Virus identification is a challenge to the clinical microbiologist since growing viruses in traditional cell culture is labor intensive, time consuming, and subject to contamination. The advent of rapid and automated immunoassays has eliminated this problem by generating positive results in minutes to hours. For example, testing for infectious mononucleosis can yield a positive result in 3-8 minutes as seen with the Beckman Coulter, Inc. ICON Mono test or in 5-15 minutes with the MONO Mononucleosis Rapid Test Device marketed by ACON Laboratories, Inc. Fully automated immunoassay analyzers provide fast, accurate, sensitive results that aid in a prompt and accurate diagnosis for the patient. Turnaround times are shortened, allowing for timely medical intervention and treatment. The priority in any hospital or medical facility is to treat the patient as quickly and appropriately as possible. By using immunoassays, clinical laboratory professionals are able to report out correct results in a timely manner, ensuring overall positive patient outcomes and improved quality of healthcare.

There are many immunoassays available that provide rapid, accurate and sensitive results. The intent of this article was to provide a brief overview of some of the products and methodologies available for clinical use and to discuss some of the principles behind the methodology and instrumentation. In the area of infectious disease, the use of immunoassays ensures rapid turnaround times that will result in the administration of prompt, accurate treatment for the patient. Ultimately, this will improve overall patient outcomes while possibly decreasing the costs associated with increased hospital stay. In conclusion, immunoassays are essentially easy to perform, cost-effective, produce highly sensitive and specific results, and allow the medical laboratory professional the ability to report accurate results in a timely manner.

Objetive. To determine the effect of fishing on capture size of both male and female Zungaro zungaro catfish, historical records of size and spatial distribution of the species were analyzed from the Orinoco Basin in Colombian. Materials and methods. Information was collected by sampling fishing port landings in the region between 1979 and 2011. Each specimen was measured, weighed and sexed. With 5411 records, the average size at capture were compared in time and among the different ports. Size at 50% maturity was estimated by quinquennium. Results. The average commercial capture sizes of Z. zungaro ranged from 35 to 161 cm standard length, with differences between males and females. From 1979 to 2011, in Puerto Lopez, the size at sexual maturity decreased from 123.8 to 83.4 cm in females and from 93.3 to 61 in males. In the annual cycle the greater average capture size in females was from April to July and for males from May to June. Average annual length is higher in the higher parts of the Meta and Guaviare river drainages. In the last quinquennium the size at 50% maturity had fallen 10 cm in females and 5 cm in males and it is higher than the average capture size. Conclusions. Populations of Z. zungaro in the Colombian Orinoco River Basin have been affected by overfishing and selective fishing of females. Source

As one can see by the tests listed at www.amp.org, molecular diagnostic techniques have enabled the laboratory professionals to play an integral role in the identification and quantitation of viral infectious agents. Viral loads can be determined for HIV, HBV, and HCV using a variety of molecular methods such as real-time PCR, TMA, NASBA, and bDNA. Determining the amount of viral particles in a sample can not only monitor the status and progression of the disease, but can also guide recommendations for antiviral therapy. Other assays listed include cytomegalovirus, enterovirus, and human metapneumovirus detection, HPV testing, influenza and respiratory virus panels, and West Nile virus detection in blood donations using a variety of molecular methodologies. The use of molecular methodologies in the detection of viral pathogens has grown at an astounding rate, especially in the past two decades. It is now widely accepted that PCR is the "gold standard" for nucleic acid detection in the clinical laboratory as well as in research facilities. This article only touched on some of the common, widely used assays and platforms used in the identification process. With more and more assays being developed, the cost behind molecular testing has decreased since there are more competitors on the market. At one point, laboratorians may have thought of routine molecular testing as the wave of the future. It is obvious the future is upon us. Molecular diagnostics has become part of the daily, routine workload in most clinical laboratories. The advent of fully automated systems with faster turn around times has given laboratory professionals the tools necessary to report out accurate and sensitive results to clinicians who can ultimately improve patient care and outcomes by rendering a correct and rapid diagnosis.

At the New Jersey Department of Health and Senior Services laboratory, clinical laboratory scientists receive specimens from various health care facilities and clinics in the state, and identify and confirm organisms of particular health concern in a rapid and timely manner. Most of the assays performed are specialized tests that are not done routinely in the clinical laboratories. Identifying and monitoring infectious agents such as West Nile virus, Influenza 2009 A (H1N1) pdm, Mycobacterium tuberculosis, enteric organisms, etc. is part of the daily workload in the Public Health Laboratories. In addition, surveillance programs are in place to control the spread of various infectious agents and to aid in investigative epidemiologic purposes. The volume of samples and workload demands can be overwhelming especially in peak months such as summer (WNV) or winter (Influenza A) therefore, it was necessary to implement molecular diagnostics and robotic technology to aid in high throughput analysis. Molecular assays have become the "norm" not only in the public health laboratories but in most clinical microbiology laboratories as well. The use of molecular diagnostics has proven advantageous resulting in accurate results, decreased turn around times, and overall better patient care and outcomes. Source
