Introduction

Medical laboratories play a crucial role in the healthcare system by providing valuable information that helps Healthcare Providers diagnose and treat patients. The correct order of draw in phlebotomy procedures is essential to ensure that blood samples are collected in the proper sequence to prevent Cross-Contamination and obtain accurate Test Results. In this article, we will explore the common tests performed in a medical lab following the correct order of draw in phlebotomy procedures in the United States.

Common Tests Performed in a Medical Lab

Medical laboratories offer a wide range of tests to assess a patient's health status and aid in diagnosis. Some of the most common tests performed in a medical lab include:

1. Complete Blood Count (CBC)

1. A complete blood count (CBC) is a commonly ordered test that provides valuable information about the number of different types of blood cells in the body.
2. It includes tests such as red blood cell count, white blood cell count, hemoglobin, hematocrit, and platelet count.
3. A CBC can help Healthcare Providers diagnose conditions such as anemia, infection, and leukemia.

2. Basic Metabolic Panel (BMP)

1. A basic metabolic panel (BMP) is a group of tests that provides information about a patient's electrolyte and acid-base balance, as well as kidney function.
2. It includes tests such as sodium, potassium, chloride, bicarbonate, blood urea nitrogen (BUN), and creatinine.
3. A BMP can help Healthcare Providers monitor patients with conditions such as diabetes, kidney disease, and electrolyte imbalances.

3. Lipid Panel

1. A lipid panel is a group of tests that measures the levels of cholesterol and triglycerides in the blood.
2. It includes tests such as total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides.
3. A lipid panel is used to assess a patient's risk of heart disease and stroke.

4. Blood Glucose Test

1. A Blood Glucose test measures the amount of glucose (sugar) in the blood.
2. It is commonly used to diagnose and monitor diabetes.
3. There are different types of Blood Glucose tests, including Fasting blood sugar, random blood sugar, and oral glucose tolerance test.

Order of Draw in Phlebotomy Procedures

The order of draw in phlebotomy procedures refers to the sequence in which different types of blood tubes are collected during a blood draw. Following the correct order of draw is essential to prevent Cross-Contamination and ensure the accuracy of Test Results. The standard order of draw in phlebotomy procedures in the United States is as follows:

1. Blood Cultures

1. Blood cultures are collected first to prevent contamination with additives from other tubes.
2. Two sets of blood cultures should be collected from separate Venipuncture sites to increase the chance of detecting pathogens.

2. Light Blue (Sodium Citrate) Tubes

1. Light blue tubes containing Sodium Citrate are used for coagulation studies, such as Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT).
2. The Sodium Citrate in these tubes prevents blood from clotting by binding calcium ions.

3. Red (No Additive) Tubes

1. Red tubes without additives are used for tests that require serum, such as blood chemistry tests.
2. The Clot Activator in these tubes promotes blood clotting, and the gel separator allows for easy serum separation.

4. Light Green or Dark Green (Heparin) Tubes

1. Light green or dark green tubes containing Heparin are used for tests that require plasma, such as electrolyte and ammonia tests.
2. Heparin prevents blood clotting by inhibiting thrombin and other clotting factors.

5. Lavender (EDTA) Tubes

1. Lavender tubes containing EDTA (ethylenediaminetetraacetic acid) are used for tests that require whole blood or plasma, such as CBC and blood bank tests.
2. EDTA is an Anticoagulant that chelates calcium ions and prevents blood clotting by binding to metal ions.

6. Gray (Potassium Oxalate/Sodium Fluoride) Tubes

1. Gray tubes containing Potassium Oxalate and Sodium Fluoride are used for tests that require plasma, such as glucose and lactate tests.
2. Potassium Oxalate and Sodium Fluoride are anticoagulants and preservatives that inhibit glycolysis and stabilize glucose levels in the blood sample.

Home Healthcare Services

Home healthcare services are becoming increasingly popular for patients who require regular monitoring and testing but prefer the convenience of receiving care in their own homes. Home healthcare services offer a wide range of medical and non-medical services, including:

1. Skilled Nursing Care

1. Skilled nursing care involves the administration of medication, wound care, and other medical treatments by a registered nurse or licensed practical nurse in the patient's home.
2. Skilled nursing care can help patients manage chronic conditions, recover from surgery, and prevent hospital readmissions.

2. Physical Therapy

1. Physical therapy is provided by a licensed physical therapist to help patients regain mobility, strength, and function after an injury or illness.
2. Physical therapy can improve balance, reduce pain, and prevent falls in elderly patients.

3. Laboratory Services

1. Home healthcare services often include laboratory services, such as blood draws and other Diagnostic Tests, that can be performed in the patient's home.
2. Home-based laboratory services provide convenience for patients who have difficulty traveling to a medical lab for testing.

4. Medical Equipment and Supplies

1. Home healthcare services may include the provision of medical equipment and supplies, such as wheelchairs, walkers, and oxygen therapy devices, to support patient care at home.
2. Medical equipment and supplies can help patients manage their health conditions and maintain independence in the home setting.

Conclusion

Medical laboratories play a critical role in the healthcare system by providing valuable diagnostic information that helps Healthcare Providers make informed decisions about patient care. Understanding the correct order of draw in phlebotomy procedures is essential for obtaining accurate Test Results and preventing Cross-Contamination. Common tests performed in a medical lab include complete blood count, basic metabolic panel, lipid panel, and Blood Glucose test. Home healthcare services are becoming increasingly popular for patients who require regular monitoring and testing but prefer the convenience of receiving care in their own homes. By following the correct order of draw and utilizing home healthcare services, patients can access timely and convenient healthcare services that meet their unique needs.
