Example 1 | |
Generic abbreviated form | NPU08839 Basocs(B)—Birch pollen induced HR; arb.am.s.(t3; proc.) = ? | |
Full form with a result | NPU08839 Basophilocytes(Blood)—Birch pollen induced Histamine Release; arbitrary amount-of-substance(t3; procedure) = low | |
Abbreviated form with a result | NPU08839 Basocs(B)—Birch pollen induced HR; arb.am.s.(t3; proc.) = low | |
Written expression | The arbitrary amount-of-substance of Birch pollen induced Histamine Release of basophilocytes in Mr Smith’s blood is [low], compared with arbitrary amount-of-substance of Birch pollen induced Histamine Release of basophilocytes in a reference system. The measurement is performed according to a procedure defined by the laboratory. Birch pollen is defined by the preparation by the Clinical & Laboratory Standards Institute (CLSI, http://ila37.clsi.org/) current code, t3. | |
