INR is a valuable measure of the liver's ability to synthesize fibrinogen and vitamin K-dependent clotting factors: factors II (prothrombin), V, VII, and X. Changes can occur rapidly because some of the involved clotting factors have short biologic half-lives (eg, 6 h for factor VII). Abnormalities indicate severe hepatocellular dysfunction, an ominous sign in acute liver disorders. In chronic liver disorders, an increasing INR indicates progression to liver failure. The INR does not increase in mild hepatocellular dysfunction and is often normal in cirrhosis. AN abnormal INR can result from coagulation disorders such as a consumptive coagulopathy or vitamin K deficiency. Fat malabsorption, including cholestasis, can cause vitamin K deficiency.
A common hematology lab test used by the CDC is the complete blood count (CBC). This test provides information about the cells in the blood, including red blood cells, white blood cells, and platelets. It can help detect a variety of conditions such as infections, anemia, and blood disorders.
Tests performed in a hematology lab include complete blood count (CBC), coagulation studies, blood typing, blood smear evaluation, and reticulocyte count. These tests help diagnose conditions such as anemia, infections, bleeding disorders, and blood cancers.
Mindray's hematology controls and calibrators are the original standards with which to evaluate the precision and accuracy of hematology analyzers. Backed up by world-class development and manufacturing, these hematology controls and calibrators offer the assurance of highest quality from your lab results. All of these hematology controls and calibrators feature long-term stability and ready-to-run tubes, and are thus convenient to use.
High RDW (red cell distribution width) on a hematology test indicates variability in red blood cell size. This can be seen in conditions such as anemia, nutritional deficiencies, or certain chronic diseases. Further evaluation is often needed to determine the specific cause of the high RDW.
The ring finger is commonly used for an INR test because it is less commonly used for tasks that may make the puncture site more prone to irritation or bleeding.
PT and INR lab test.
The INR has basically replaced the prothrombin time, or PT.

INR is "International normalized ratio": it is a test for blood coagulation.

Depend
differential distinguishes between mature and imature white blood cells and can detect abnormal cells. A differential is usual needed when a white blood cell count is low.
INR
A light microscope is typically used in a hematology lab for examining blood samples. This type of microscope allows for visualization of red blood cells, white blood cells, and platelets in order to perform various blood tests and analysis.
