What is this test?
This is a medication-history measure rather than a blood test. It records the number of anticoagulant doses received during the previous 7 days, or since admission or reentry if that was less than 7 days.
Why might I need this test?
Clinicians may use it during medication reconciliation or when planning hospital care. It can help confirm that blood-thinning medicines are being taken correctly and identify possible bleeding or clotting risks.
How is the test performed?
The information is obtained by reviewing the medication record, medication list, administration record, or other available documentation. The number of anticoagulant doses received is then entered into the appropriate clinical record.
How do I prepare for the test?
No special preparation or fasting is required. Bring an updated list of your medicines and, if available, information about the dates and times you take your anticoagulant.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This count is not an abnormal laboratory result, but discrepancies may indicate incomplete medication reconciliation or possible improper use of an anticoagulant. Missing, extra, or incorrectly timed doses may affect the risk of bleeding or clot formation and should be reviewed with the treating clinician.
Short name
