A new test for anemia able to provide a diagnosis from a speck of blood could make it easier for people to monitor the disease from home.
The device will be made up of two pieces. After the patient pricks a finger with a small lance, the device's cap (a small vial) will be used to draw in a specific amount of blood by capillary action. The cap with the blood sample will then be connected to the test kit, where it will be mixed with a chemical reagent that will change color depending upon the amount of hemoglobin in the blood.
