Instant Blood Test

To a doctor, a patient's blood sample is a special index. Medical analysis of a blood count can help to spot various infections, diseases and even some types of cancer. Usually doctors have to wait hours and sometimes days to test a blood sample. But now even untrained medical workers can perform on-the-spot blood tests and get results in minutes thanks to newly developed electronic instruments. Doctors devised a diagnostic system that consists of a centrifuge and an incubator for blood samples, and a reader that can diagnose the condition of the blood. The reader is a version of a microscope connected to an ultraviolet light source. When beamed to the blood sample through filters, the light is able to detect red cells, white cells and platelets, the blood clotting component. Then computerized sensors can automatically measure these components.

All that a medical technician must do is look through the microscope eyepiece. According to the developers, blood test analysis with this system may take about 15 minutes.

Instant diagnoses are the object of recent research.

Japanese scientists designed an instrument which can detect the presence of cancer within a few minutes. A special reagent must be used. It coagulates the blood and the results of the analyses are displayed on the screen.

Exercise 2. Answer the questions.

1. Does a patient's blood sample help a doctor to diagnose the disease? 2. What can help the doctor to detect various infections, diseases and even some types of cancer? 3. Who can perform on-the-spot blood tests? Why is it important? 4. Are the on-the-spot tests difficult to perform? Why? 5. Do you think that such diagnostic instruments may be the instruments of the future?
