Example 1 | |
Generic abbreviated |
NPU21422 Culture(Lymcs; B)—Concanavalin A stimulated lymphocytes; rel.num.ratio(actual/norm; proc.) = ? | |
Full result |
NPU21422 Culture(Lymphocytes; Blood)—Concanavalin A stimulated lymphocytes; relative number ratio(actual/norm; procedure) = 0.46
|
|
Abbreviated result | NPU21422 Culture(Lymcs; B)—Concanavalin A stimulated lymphocytes; rel.num.ratio(actual/norm; proc.) = 0.46 | |
Written expression | The relative number ratio of Concanavalin A stimulated lymphocytes in a culture from Mr. Smith’s blood is [0.46]. The calcuation is performed by dividing the number ratio of Concanavalin A stimulated lymphocytes in a culture from Mr. Smith’s blood with number ratio of Concanavalin A stimulated lymphocytes in a culture from a norm. The measurement is performed according to procedure defined by the laboratory. | |

Notes
|
“Actual” refers to the culture from the actual patient’s (Mr. Smith’s) blood, “Norm” refers to a reference system. |
