Yes, a lavender top tube can be used for prothrombin time (PT) and activated partial thromboplastin time (PTT) tests. Lavender top tubes contain EDTA, an anticoagulant that helps preserve the blood sample for accurate coagulation testing. However, some laboratories prefer using specific tubes, like blue top tubes for PT and PTT, to ensure optimal test performance, so it's best to confirm with the testing facility.

What color of tubes is used for PT and PTT blood draw?
light blue top tube
In hematology what is PT and PTT?
Prothrombin time (PT) and partial thromboplastin time (PTT) tests are used to evaluate the extrinsic coagulation system
What do the medical abbreviations pt and ptt mean?
Prothrombin time (PT) and partial thromboplastin time (PTT) are tests that are used to evaluate the extrinsic coagulation system.
What are the PT and PTT laboratory tests used to monitor?
PT (prothrombin time) and PTT (partial thromboplastin time) tests are used to monitor the function of the blood clotting system and to assess the risk of bleeding or clotting disorders. PT is generally used to monitor the effectiveness of anticoagulant therapy, while PTT is used to evaluate the intrinsic pathway of coagulation and monitor heparin therapy.
What color tube is used for a pt?
A lavender or pink top tube is typically used for a PT (prothrombin time) test. This is the color used for collecting samples for coagulation studies.
Hypofibrinogenemia affect on pt ptt results?
Patients with low levels of fibrinogen have prolonged PTT in most cases.
Why ptt is higher than pt?
PTT (partial thromboplastin time) is typically higher than PT (prothrombin time) because they measure different aspects of the clotting process. PTT assesses the intrinsic and common pathways of coagulation, while PT evaluates the extrinsic and common pathways. Conditions affecting the intrinsic pathway, such as deficiencies in factors VIII, IX, or XI, can prolong PTT without impacting PT. Additionally, PTT is more sensitive to certain anticoagulants and disorders, leading to higher values in specific clinical scenarios.
What test is performed in the Coagulation Department?
PT/PTT and INR

Does Ritalin cause bruising?
Not likely. Bruising can be caused by abnormal clotting factors. PT and PTT can be measured and if they are nl then the bruising is probably not related to the Ritalin. It would be highly unlikely for Ritalin to affect the PT or PTT. Actually, Ritalin does cause bruising. This is a rare but serious side effect and you should stop taking the drug immediately and contact your doctor. The PT and PTT may show up normal but once the Ritalin is discontinued, the bruising typically stops.
Light blue top tube would least likely be used for?
A light blue top tube would least likely be used for collecting blood samples for coagulation studies, as these typically require a blue top tube containing sodium citrate for anticoagulation. Light blue top tubes are commonly used for coagulation studies (PT/INR, PTT) and may contain citrate to prevent clotting of the sample.
