Methods to accurately diagnose this condition are inadequate in these regions. The Sally Centrifuge, with its mechanically-powered, cost-efficient and portable design, hopes to bring accurate diagnostic technology to low-resource areas.\n\n== Detailed description of the solution ==\n\nThe Sally Centrifuge is composed of hair combs, a salad spinner and a round plastic container. It spins small capillary tubes filled with blood for ten minutes with manual pumping. A rudimentary gauge is then used to assess hematocrit values (or the ratio of red blood cells to the total volume) to determine whether a person is anemic. The centrifuge can spin up to 30 samples in ten minutes at a rate of 950 rpm.\n\n== Describe its relevance to resource-constrained settings ==\n\nThe Sally Centrifuge is optimal for use in resource-constrained settings because it does not require electricity. It is inexpensive, lightweight, portable, robust and fairly easy to operate. Moreover, studies have shown that it is considerably accurate and effective.\n\n== Designed by ==\n\n* Designed by: Lauren Theis and Lila Kerr, two undergraduate students of Rice University's 360: Institute for Global Health Technologies\n\n== References ==\n\n=== Peer-reviewed publication ===\n\nBrown, J., Theis, L., Kerr, L., Zakhidova, N., O'Connor, K., Uthman, M.
