Red Blood Cell Count Test
This test measures the number of red blood cells in a whole-blood sample. It is part of a complete blood count and can be ordered through Celio Health.
About this test
The test analyzes a blood sample collected in an EDTA (lavender-top) tube, using electronic cell counting, cytometry or microscopy to determine the number of red blood cells present. It reports a single count.
Quest lists this measurement as part of a complete blood count, used as a screening test for conditions such as anemia, leukemia and inflammatory processes. A red blood cell count on its own is one piece of a complete blood count picture, which is why it is commonly read alongside the other values that make up that panel.
