| description | The maximum clot strength in the presence of arachidonic acid, as measured by the amplitude of resonance of the blood meniscus as the blood sample clots. In this test, thrombin activity is blocked, and arachidonic acid (AA) is used to activate platelets in order to measure the clot strength based on platelet activation by AA, which result is used to determine the relative contribution of AA-induced platelet activation [LOINC: 94579-0] to the overall clot strength [LOINC: 91125-5]. This term was created for, but is not limited in use to, the Submitter's test kit, the TEG6s PlateletMapping ADP & AA Assay Cartridge for heparinized blood. | |

Fully-Specified Name | ||
| component | Maximum clot strength amplitude | |
| property | Len = Length | |
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | |
| system | Bld = Whole blood | |
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | |
