Clinical Decision Support System

This article explains the key concepts and practices involved in making laboratory tests reliable.
How Reliable is Laboratory Testing? Lab test results play a crucial role in medical decision-making. Deciphering Your Lab Report This article includes an interactive sample lab report that provides explanations of the elements found on a typical lab report. This article explains the difficulty in defining and using reference ranges. SmrtX Medical Tests Analyzer is the complete solution for efficient, reliable and modern managing of patient's medical lab results history.Reference Ranges and What They Mean Lab test results are often interpreted on their relation to a reference range.

Levels that are abnormally high or low could indicate that you're in danger of bleeding or getting blood clots in your blood vessels. Blood clotting tests are also used to track the health of people who take medications to reduce their risk of blood clots. There is no critical level for a D-dimer.
Prothrombin time (PT)/INR test
PT test determines how long it takes for a blood clot to form in a blood sample. An INR is a calculation based on PT test results.
PT: 11 to 13.5 seconds
INR: 0.8 to 1.1
Activated partial thromboplastin time test
PT test determines how long it takes for a blood clot to form in a blood sample. An INR is a calculation based on PT test results.
A normal range is between 21 and 35 seconds.Two examples of such medications are heparin and warfarin.
Doctors frequently order blood clotting tests (coagulation tests) such as:
D-dimer test
Detects D-dimer in the blood (a protein fragment formed in the body when a blood clot dissolves)
A normal D-dimer is considered 0.50
As D-dimer is a screening test, a positive D-dimer is a positive screen. Blood clotting tests look for proteins in your blood that affect how your blood clots.
