How Is Hit Diagnosed

HIT can often be diagnosed by measuring the platelet count and PF4 antibody level in the blood. Symptoms of new blood clot formation may suggest HIT. Symptoms of deep vein thrombosis include pain or tenderness, sudden swelling, discoloration, visibly large veins, and skin that is warm to the touch.

What are the warning signs of HIT?

• Skin tenderness.
• Swelling.
• Skin that’s warm to the touch.
• Shortness of breath.
• Change in heart rate.
• Sharp pain in your chest.
• Dizziness.
• Anxiety.

Is HIT hereditary?

Genetic studies have not consistently identified risk alleles for HIT, the production of platelet factor 4/heparin antibodies or the thromboembolic complications of HIT.
