The QBC Malaria Tube is internally coated with all the necessary reagents and anticoagulants to perform a malaria test in minutes. The QBC Malaria Tube contains a fluorochrome called Acridine Orange and anticoagulants - when a capillary or venous blood sample is added, a precision engineered plastic float is inserted into the QBC Malaria Tube. When the QBC Malaria Tube is centrifuged, the blood becomes concentrated and the precision float sits level with the Buffy Coat layer. The blood components and malaria parasites separate based on density and concentrate in distinct layers. Parasites and leucocyte nuclei fluoresce a yellowish-green. It is in the Buffy Coat layer where the malaria parasites will be visible. Using the QBC Malaria Tube under an LED fluorescent microscope (such as the QBC ParaLens Advance) identification of the following parasites is possible: Malaria (P. falciparum, P. vivax, P. malariae, P. ovale) Babesiasis: (B. microti, B. bigemina), Typanosomiasis (T. brucei, T. gambiense, T. rhodensiense, Crithidia species, T. cruzi), Filariasis (W. bancrofti, B. malayi, Loa loa, M. ozzardi, M. perstans, D. immitis) Borrelia (B. duttonii, B. crocidurae). The float occupies the area midpoint between red cells and plasma. The amber layer surrounding the float is the buffy coat. Seen enlarged above, the three separate layers of the buffy coat are comprised of orange-yellow fluorescing platelets (top), green lympocytes/monocytes (middle) and yellow granulocytes (bottom). Below the granulocytes is the red blood cell layer (some overlap of RBC's and granulocytes occurs). Red cells containing Plasmodium parasites concentrate at the top of this layer and appear as multiple "pinpoints" of fluorescence. A negative specimen shows no fluorescing points in this area.
