What is the ratio of a sample of red blood cells in dilute blood?(a) 5

1.	What is the ratio of a sample of red blood cells in dilute blood?(a) 500:1(b) 50000:1(c) 1:500(d) 1:50000I had been asked this question in unit test.My doubt is from Intravascular Oximeters topic in chapter Oximeters of Biomedical Instrumentation
Answer» The correct option is (d) 1:50000 Easiest EXPLANATION: The method is based on collecting scattered light from the blood CELLS and converting them into electrical pulses for COUNTING. A sample of dilute blood (1:500 for white cells and 1:50,000 for red cells) is taken in a GLASS container. It is drawn through a counting CHAMBER in which the blood stream is reduced in cross-section by a concentric high velocity liquid sheath.
