A functional microscope is the most important and most expensive piece of equipment required for smear microscopy. Global Fund monies have provided a unique opportunity to equip laboratories in low-resource countries, but these funds must be spent wisely. Cheap microscopes are superficially appealing. However, higher-quality microscopes generally have better optics and last longer. International agencies should consider establishing a purchasing service to assist countries in their microscope procurement. Such a system would provide quality assurance and increased purchasing power.
