Note: Reagents are required if stains are to bemade by the technician power is not available, an alternate must be considered. Solar powered refrigerators are one possibility. Much of the equipment listed in the suitcase has been chosen for its ability to be reused. All glassware, slides, ESR tubes, urine bottle, gloves, pipette tips, etc. can be cleaned, dried and reused. This recycling minimizes the amount of equipment that needs to be transported (Fig. 2). Organizing and Setting Up the Lab A clean, flat surface is necessary when setting up the lab. If a bench top or table is not available, a flat section of ground covered with a clean sheet will suffice. If a room is available, it will optimally include a power and water supply and refrigerator. Large windows covered with fly nets will make the working atmosphere more enjoyable and provide good lighting. In short, a simple room in either a building or dwelling will do quite nicely.

Lab in a Suitcase Figure 1. The phase contrast microscope. Preparing Blood, Plasma and Serum Various procedures will require different sample. If whole anticoagulated blood is needed mix (by inverting gently) 4.5 ml blood with 0.5 ml citrate saline. This will prevent clotting of the sample. If plasma is needed allow the anticoagulated blood sample to sit upright for 2-3 hours. The cells will sediment in the lower half of the tube with plasma on top. If a centrifuge is available, spin the tube at 1000 rpm for 10 min. To isolate serum, obtain a blood sample with no additives. Allow blood to clot for 1 hour and let sit upright for 2-3 hours to allow for separation of cells and serum. As with plasma, serum will be the top layer in the tube. Blood Typing and Transfusion One of the most important and potentially life saving procedures is blood typing and transfusion. It is important to quickly determine the blood type of the parent 61 Figure 2. Re-used glass urine bottles. 8
