Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.
Laboratory tests might include: full blood count, liver enzymes, renal function and erythrocyte sedimentation rate. [citation needed] If the cause for the high platelet count remains unclear, bone marrow biopsy is often undertaken, to differentiate whether the high platelet count is reactive or essential.

Platelet concentration in the blood (i.e. platelet count), can be measured manually using a hemocytometer, or by placing blood in an automated platelet analyzer using particle counting, such as a Coulter counter or optical methods. [47] Most common blood testing methods include platelet count in their measurements, usually reported as PLT. [48]
Platelets are regulators of hemostasis and thrombosis. Platelets become active in the blood following vascular injury. Vascular injury causes platelets to stick to the cellular matrix that is exposed under the endothelium, form a platelet plug, and then form a thrombus. Platelets are essential in the formation of an occlusive thrombus and are ...
In a typical set of rules, a platelet donor must weigh at least 50 kg (110 lb) and have a platelet count of at least 150 x 10 9 /L (150,000 platelets per mm³). [2] One unit has greater than 3×10 11 platelets. Therefore, it takes 2 liters of blood having a platelet count of 150,000/mm³ to produce one unit of platelets.
Hydroxycarbamide, interferon-α and anagrelide can lower the platelet count. Low-dose aspirin is used to reduce the risk of blood clot formation unless the platelet count is very high, where there is a risk of bleeding from the disease, and hence this measure would be counter-productive as aspirin-use increases the risk of bleeding. [3] [15 ...
Despite this, several things are associated with liver angiosarcoma. Exposure to vinyl chloride, arsenic, thorotrast, radium, phenylhydrazine and use of androgens is known to contribute to the pathogenesis of liver angiosarcoma. [2] Cyclophosphamide, [4] diethylstilbestrol and oral contraceptives use are also associated with liver angiosarcoma ...
Surgical removal of the tumor is associated with better cancer prognosis, but only 5–15% of patients are suitable for surgical resection due to the extent of disease or poor liver function. [58] Surgery is only considered if the entire tumor can be safely removed while preserving sufficient functional liver to maintain normal physiology.
