Hematological tests that require venipuncture include complete blood count (CBC), blood typing and crossmatching, and coagulation studies such as prothrombin time (PT) and activated partial thromboplastin time (aPTT). These tests assess various components of blood, including red and white blood cells, platelets, and clotting factors. Venipuncture is preferred over capillary sampling for these tests due to the larger volume of blood needed and the need for accurate results.

What two types of blood specimens are used for most hematological tests?
The two main types of blood specimens used for most hematological tests are whole blood and plasma. Whole blood includes all components of blood, while plasma is the liquid portion of blood after cells have been removed.
What are heamatological tests?
Hematological tests are laboratory analyses that evaluate the components and functions of blood. These tests typically include complete blood counts (CBC), which measure red blood cells, white blood cells, hemoglobin, hematocrit, and platelets, as well as tests for blood clotting and various blood disorders. They are essential for diagnosing conditions such as anemia, infections, and hematological diseases like leukemia. Overall, hematological tests provide critical information about a person's health and help guide treatment decisions.
What do hematological tests measure?
Hematological tests measure various components of blood, including red blood cells, white blood cells, platelets, hemoglobin, and hematocrit levels. These tests help evaluate overall health, diagnose conditions such as anemia or infections, monitor treatment effectiveness, and detect disorders like leukemia or clotting disorders.
What is used to prepare the skin prior to a venipuncture when alcohol causes inaccurate results for certain tests?
Soap and water
What does routine venipuncture test for?
Routine venipuncture tests typically assess various blood components to evaluate a person's overall health. Common tests include complete blood count (CBC), metabolic panels, and lipid profiles, which help identify conditions like anemia, diabetes, and cholesterol levels. Additionally, these tests can provide crucial information about organ function and detect infections or other underlying health issues. Overall, routine venipuncture serves as a valuable tool for preventive care and diagnosis.
What are the different types of tubes used for blood collection and how do they differ in terms of their purpose and composition?
There are several types of tubes used for blood collection, including EDTA tubes, serum tubes, heparin tubes, and plasma tubes. These tubes differ in their purpose and composition. EDTA tubes are used for collecting blood for complete blood counts and other hematological tests, containing an anticoagulant called EDTA. Serum tubes are used for tests that require serum, such as chemistry tests, and do not contain any anticoagulant. Heparin tubes contain the anticoagulant heparin and are used for tests that require plasma, such as coagulation studies. Plasma tubes also contain an anticoagulant and are used for tests that require plasma, such as glucose testing.
Can dermal puncture and venipuncture collections be alternated on a patient receiving h and h tests?
If you are trying to compare numbers from one draw to the next, it would be best to use the same procedure each time. Dermal puncture and venipuncture can give different answers depending on technique.
What professional does hemoglobin tests?
A nurse or phlebotomist usually collects the sample by inserting a needle into a vein, or venipuncture, after cleaning the skin, which helps prevent infections.
When do you use a 23 gauge needle on a venipuncture?
A 23-gauge needle is typically used for venipuncture when accessing smaller veins, such as those found in pediatric patients or patients with fragile veins. It is also preferred for drawing blood when minimizing trauma is a priority, as it causes less damage to the vessel compared to larger gauge needles. Additionally, a 23-gauge needle may be suitable for specific laboratory tests that require a smaller volume of blood.
Why should the alcohol applied be allowed to dry before performing a venipuncture?
Allowing the alcohol to dry before performing a venipuncture helps to ensure that the area is properly disinfected, reducing the risk of introducing bacteria into the bloodstream. Additionally, wet alcohol can interfere with some blood tests by diluting the blood sample.
What tests are done in a lavender tube?
A lavender tube typically contains an additive called EDTA and is used for collecting whole blood for hematological testing, such as complete blood count (CBC), blood typing, and blood cell morphology examination. It is commonly used for tests that require anticoagulated whole blood samples.
Does UCLA require subject tests?
