What is creatinine
A waste product stored in the muscles as creatine phosphate and then converted to creatinine.
LFT is
Liver function test
Platelets are?
Small cell fragments that do not contain a nucleus and are responsible for the generation of the plug which forms at the site of a puncture
A high INR, around 5, indicates?
There’s a high chance of bleeding
A low INR indicates?
There’s a high chance of clot formation
A positive D-dimer indicates
The presence of an abnormally high level of fibrin degradation products in the body.
Indicates that there is a significant thrombus formation and breakdown in the body.
What lab value indicates that the D-dimer is negative
