Hepatitis B platelets of 104X10^9/L are normal. Usually the normal value of platelets is between 100X10⁹/L and 300X10⁹/L, so when the platelet value of hepatitis B patients is 104X10⁹/L, it is normal to be in the normal range value. When the hepatitis B virus attacks the liver for a long time resulting in repeated damage to liver cells, it is easy to cause necrosis of liver cells, nodular regeneration, fibrous hyperplasia after the eventual formation of cirrhosis. As cirrhosis may lead to hyperfunction of the spleen, it is easy to remove red blood cells, platelets and other substances together, which leads to a decrease in the number of platelets, abnormalities in coagulation and hemostasis, and easy to develop skin petechiae, ecchymosis, purpura and other symptoms. If the platelet value of hepatitis B patients is abnormal, they should go to a professional hospital in time, after clarifying the cause of the disease, and then carry out systematic treatment under the guidance of doctors.
