 Example 1
Generic abbreviated form NPU01944 B—Erythrocytes; entitic vol. = ? fL
Full form with a result NPU01944 Blood—Erythrocytes; entitic volume = 90 femtolitre
Abbreviated form with a result NPU01944 B—Erythrocytes; entitic vol. = 90 fL
Written expression The volume of Erythrocytes divided by number of Erythrocytes in Mrs. Smith’s blood is [90] fL.
Equation

 
Notes Alternative expression: The average volume of Erythrocytes is [90] fL
Example 2
Generic abbreviated form NPU03562 B—Thrombocytes; entitic vol. = ? fL
Full form with a result NPU03562 Blood—Thrombocytes; entitic volume = 9 femtolitre
Abbreviated form with a result NPU03562 B—Thrombocytes; entitic vol. = 9 fL
Written expression The volume of Thrombocytes divided by number of Thrombocytes in Mr. Smith’s blood is [9] fL.
Equation
Notes Alternative expression: The average volume of Thrombocytes is [9] fL.
Example 3
Generic abbreviated form NPU17013 B—Reticulocytes; entitic vol. = ? fL
Full form with a result NPU17013 Blood—Reticulocytes; entitic volume = 101 femtolitre
Abbreviated form with a result NPU17013 B—Reticulocytes; entitic vol. = 101 fL
Written expression The volume of Reticulocytes divided by number of Reticulocytes in Mr. Smith’s blood is [101] fL.
Equation
Notes Alternative expression: The average volume of Reticulocytes is [101] fL.
