If a client presents with petechiae and ecchymoses, these are signs of possible coagulation disorders. The following laboratory tests are typically expected:

1. Complete Blood Count (CBC): This is usually the first test ordered. It can provide information about the number of different blood cells in the body. Low platelet count (thrombocytopenia) can cause petechiae and ecchymoses.

2. Coagulation Tests: These include Prothrombin Time (PT), International Normalized Ratio (INR), and Activated Partial Thromboplastin Time (aPTT). These tests measure how long it takes for blood to clot. If the blood takes longer than normal to clot, this could be a sign of a coagulation disorder.

3. Platelet Function Tests: These tests assess how well the platelets are working. If the platelets are not functioning properly, this could lead to petechiae and ecchymoses.

4. Fibrinogen Level Test: Fibrinogen is a protein that helps in the clotting process. Low levels can indicate a problem with the body's ability to form clots.

5. Factor Assays: These tests measure the activity of specific clotting factors. Deficiencies in these factors can lead to coagulation disorders.

6. D-dimer Test: This test can be used to rule out conditions like disseminated intravascular coagulation (DIC), which can also cause petechiae and ecchymoses.

Remember, the specific tests ordered can vary depending on the patient's symptoms, medical history, and the physician's clinical judgment.
