What is the reason for the red spots on the nails?

If there are red spots inside the nails, it is usually due to bruises caused by trauma or other reasons. You don't need to pay too much attention to it at this time, and it will gradually get better over time. However, you must be alert to whether it is caused by platelet abnormalities or a lack of trace elements. If the platelets are abnormal, it may cause many bleeding spots. You must pay attention at this time and go to the hospital for examination in time.

What is platelet abnormality

Qualitative platelet defects are a group of bleeding diseases caused by defects in platelet adhesion, aggregation, release, procoagulant function and arachidonic acid metabolism. It is divided into two categories: congenital and acquired, and most of the children have congenital hereditary diseases. The common feature is that the platelet count is high but there is no obvious decrease, while the platelet function test is abnormal: such as prolonged bleeding time, decreased prothrombin consumption, poor thromboplastin generation, and a positive arm test. However, the coagulation time, prothrombin time, thrombin time and partial thromboplastin time were all normal.

Disease Introduction

In this disorder, the number of platelets is normal, but they cannot form blood clots normally and bleeding is prolonged. Abnormal platelet function may be due to endogenous platelet defects or due to exogenous factors that change normal platelet function. Platelet defects may be inherited or acquired. Tests of the coagulation phase of hemostasis (eg, PTT and PT) are normal in most, but not all, cases.
