Managing Editor and Clinical Lead

Woodley Laboratory Diagnostics and QBC Europe have announced the availability of the new QBC F.A.S.T Malaria Stain, a fluorescent stain that revolutionises malaria detection with features that provide a fast, clear alternative to standard Giemsa stains.

Malaria parasites stained with F.A.S.T. Malaria Stain glow bright gold or orange against a dark background maximising contrast during review. The use of fluorescence microscopy improves clarity and contrast; and with minimal artefact staining, users are focused on parasites in the sample.

The F.A.S.T Malaria Stain is designed for use with a fluorescent microscope. For those without a suitable microscope, the QBC Paralens Advance LED Fluorescence microscope attachment is available with a 100x objective and can be attached to any standard light microscope.

The Malaria Stain is available in 120 mL, 250 mL, and 3.8 L bottles with each test requiring 0.5 mL of stain, thus the bottle sizes providing 240, 500, and 7,600 tests respectively. It contains no methanol, is not flammable, and has a shelf life of 1 year from the date on manufacture.

QBC Malaria Kits

Woodley Equipment Company Ltd

The QBC Malaria Test represents a revolution in malaria and other blood borne parasite testing technology. This simple to use test contains all of its staining agents within a single tube, thereby making testing faster and easier. Clinicians on the frontline of the malaria battle need fast results. The QBC Malaria Test leaves other malaria testing options in the dust in terms of preparation time and time required for review. The test itself can be prepared in just 6-7 minutes, as it requires only to be filled with finger stick blood then centrifuged in the QBC Centrifuge for 5 minutes. The test can then be analysed under a fluorescent microscope (we recommend our QBC ParaLens Advance Fluorescent Microscope System). Since the tube has been concentrated by centrifugation, the malaria parasites will be concentrated. Experienced technicians are capable of declaring a sample negative in just 3 minutes. At just 9-10 total minutes, the QBC Malaria Test can be performed in a third of the time of existing products. These tubes are designed for use with the QBC Paralens Advance System

QBC ParaLens Advance Fluorescent Microscope Attachment

Woodley Equipment Company Ltd

The QBC ParaLens Advance microscope attachment is a unique solution to fluorescence microscopy in that it combines the critical components of an epi-fluorescence microscope, namely the light source and filter set, with a microscope objective in a compact, durable format that can transform virtually any compound light microscope into an epi-fluorescence microscope. Utilising LED technology, the ParaLens light source lamp has a life of 20,000 hours, far exceeding that of standard fluorescence scopes, and can be powered by low voltage DC sources, such as a solar pack or laptop computer USB port. Moreover, the LED source is mercury-free and produces no UV radiation. Designed for Functionality: The ParaLens Advance is available with a light source-filter combination that supports fluorescence applications that utilise blue excitation and emission light in the green to red spectrum (e.g., FITC fluorescence). This combination allows for a very broad range of applications such as TB detection, malaria diagnosis, indirect fluorescence assays, antibody-based staining studies, gene/protein expression studies, water testing, and many other functions. The attachment is available with 40x, 60x (oil), and 100x (oil) objectives and a solar/battery pack power source, as well as USB, car cigarette lighter, and battery clamp power cords are available for use in resource limited settings. The ParaLens is packaged in a rugged custom case that is perfect for transport and storage in the field and other rough settings.

QBC F.A.S.T. Malaria Stain

Woodley Equipment Company Ltd

The QBC F.A.S.T. Malaria Stain is a fluorescent stain that revolutionises malaria detection with features that provide a fast, clear alternative to standard Giemsa stains Malaria Staining in Minutes Improved Clarity Simple Training Requirements The QBC F.A.S.T. Malaria Stain uses fluorescence microscopy to improve clarity and contrast in malaria detection. Malaria parasites stained with F.A.S.T. stain stand out clearly against a dark background. The stain also provides unmatched speed, with thin blood film staining in just 1 minute, and minimising training requirements by utilising the same basic thin and thick smear preparation and review techniques as Giemsa stain. Designed for use under a fluorescent microscope or the QBC ParaLens Advance System. How Does It Work? The QBC F.A.S.T. Malaria Stain's propritary blend allows it to quickly permeate blood cells and bind to the nucleic acid of malaria parasites. When excited by blue light (~400-480 nm), stained parasites will fluoresce bright gold or orange, making them easy to detect.
