Liposom· Immunoassay Group A Strep Test Delivers Highly Accurate Results
BBL Microbiology Systems, division of Becton Dickinson and Company announces the first liposome immunoassay color<hange test for the detection and confirmation of Group A Streptococci. The new test, called Directigen 1-2-3m, delivers highly sensitive color-change readings within one minute after extraction of a sample.
BBL liposome immunoassay technology is based on high efficiency engineering which uses dye-filled liposomes, sensitized with antibodies, to bind to antigen extracted from organisms on throat swab specimens. The high sensitivity of this process means that the liposomes will trigger the distinct color reaction even when only low levels of antigen are present.
Directigen 1-2-3 reagents are so stable that they are stored at room temperature, thus requiring no refrigerated storage space. All reagents and components come fully prepared for use. and require no warming, thawing, dilution, or preparation. The Directigen 1-2-3 liposome detection process is extremely simple and straightforward. Detection of Group A Strep antigen is performed and read in the ColorPAC™ triangular testing device. The entire streamlined three-step procedure is to dispense three órops each of specimen, liposome detection reagent, and liposome wash reagent into the ColorPAC. There is no timing required between each step. Distinctive positive or negative readings appear immediately as the wash is added.
Both the triangle (positive reading) and the control dot (negative reading) contain built-in quality control that confirms proper execution of the test and the active condition of the detection reagent. If the test is incorrectly performed, or if the test components are inactive, nothing will appear. For additional laboratory quality control, a separate positive antigen control is provided in the kit.

FirstTemp Makes Oral/ Rectal Thermometers Obsolete
FirstTemp is a revolutionary noninvasive thermometer that instantly senses the infrared emissions of the tympanic membrane. When placed gently at the opening of the ear, FirstTemp takes a reading of the body's core temperature in one second. It is accurate because the tympanic membrane shares the blood supply that reaches the hypothalamus, which controls body temperature.
Unlike the mouth or rectum, the ear canal has no mucous membrane, a source of potential contagion. Furthermore, the FirstTemp probe is covered with a comfortable, sanitary, disposable speculum that fits aduits and infants safely. It is applied and ejected without being touched.
In clinical trials at the University of Vermont, FirstTemp was tested alongside both a Swan-Ganz catheter in the pulmonary artery and an indwelling rectal thermometer. FirstTemp proved extremely accurate, supporting the statements of earlier investigators that noninvasive tympanic thermometry would likely deliver the quickest, most reliable correlation with the body's core temperature.
At the flick of a switch. FirstTemp becomes a surface-scanning instrument. Without touching the skin, medical personnel can obtain the temperature of the area within FirstTemp s target field of view This can be invaluable in the assessment of burn sites, vascular integrity, or IV infiltration.

New Olympic Smart Scale Model 30
The new Olympic Smart Scale Model 30, only 1.3 inches high, monitors an infant's weight with one gram accuracy in an incubator or radiant warmer. The Smart Scale consists of a weighing platform connected to a display/control unit by a 6 foot cable. The display/ control unit mounts on an I.V pole or can be set on a shelf.
Pressing a button starts the automatic weighing sequence. A 15second delay gives the nurse time to lift any I.V. tubes or monitor leads attached to the infant before the weighing begins. Smart Scale uses a sensitive load cell in the weighing platform, coupled with a microprocessor in the display/control unit to accurately compute the baby's weight.
Syva MicroTrak® Direct Specimen lest for Suspected Chlamydial Infections in Newborns
Syva Company introduces a new protocol for the Syva MicroTrak® Chlamydia trachomatis Direct Specimen Test. Chlamydial disease in newborns now can be diagnosed by the detection of elementary bodies in specimens collected by nasopharyngeal swab or aspirate, or by conjunctival swab. These body sites are the most likely to be positive for chlamydia if the infant has been infected.
Chlamydia trachomatis has been implicated in neonatal conjunctivitis and afebrile pneumonia. One third to one half of all babies born vaginally to mothers with chlamydia will be infected; most of these infected neonates will develop conjunctivitis or respiratory tract infection that can lead to afebrile pneumonia.
The Syva MicroTrak® direct specimen test provides a simple, rapiö procedure for the earliest possible diagnosis of chlamydial infections in newborns. Once the specimen reaches the laboratory, test results can be obtained within 30 minutes.
The direct specimen test is comparable in performance to conventional cell culture methods and requires no special equipment other than a fluorescence microscope. When swab or aspirate specimens are applied directly to the slide well and stained, antibody conjugate binds specifically to any Chlamydia trachomatis organisms present in the smear. Under a fluorescence microscope, positive specimens will appear as bright apple-green elementary bodies on a background of reddishbrown counterstained cells.

Pediatric Emergency Crlcothyrotomy/ Tracheostomy Device
Pedia-Trake™ is an emergency cricothyrotomy/tracheostomy device for use on children I to 8 years of age. It is the only device available on the market today to perform this procedure on children.
Pedia-Trake™ establishes an airway in an emergency situation within 20 seconds, providing safe and easy entry into the trachea and eliminating many complications such as overpenetration, tissue damage, and excessive bleeding. Once entrance has been made into the trachea, the airways are interchangeable without having to redefine or repenetrate the trachea.
Pedia-Trake™ is a reusable device that is packaged in a sterilized kit for emergency use and features individually wrapped and interchangeable airway sizes of 3mm, 4mm, and 5mm I.D. for providing effective ventilation. Tubes with obturators are color coded for easy identification and can be attached to a universal adapter. Kit also contains a replacement set of a stylet, syringe, and scalpel. Both the tubes and replacement sets are available for reorder.
