Blood tests before surgery are a routine part of the preoperative evaluation process and are designed to assess a patient’s overall health status and identify any potential risks associated with the surgical procedure. The purpose of these tests is to help ensure that the patient is fit for surgery and that the surgery can be performed safely and effectively.

Common Pre Surgery Blood Tests

Blood Count – One of the main reasons for performing blood tests before surgery is to check the patient’s blood count. This involves measuring the number of red blood cells, white blood cells, and platelets in the blood. A low red blood cell count can indicate anemia, which may require treatment prior to surgery, while a low white blood cell count can indicate an infection or other underlying medical condition. A low platelet count can increase the risk of bleeding during and after surgery, so it is important to identify this prior to the procedure.

Coagulation – Another important blood test that is typically performed before surgery is a coagulation test. This test measures how well the blood is able to clot, and is important because it helps identify patients who may be at an increased risk of bleeding during and after surgery. Patients who are found to have a coagulation disorder may need to undergo additional testing or may need to receive medication to help prevent excessive bleeding.

Organ Function & Electrolytes – Blood tests can also be used to assess a patient’s kidney function, liver function, and electrolyte levels. Abnormalities in any of these areas can increase the risk of complications during and after surgery and may require additional monitoring or treatment.

Infectious Disease – Blood tests can be used to screen for infectious diseases such as HIV, hepatitis B and C, and syphilis. Identifying these infections prior to surgery is important, as it allows the healthcare team to take appropriate precautions to prevent the spread of the infection to others, and to ensure that the patient receives appropriate treatment.

Quick Summary

Blood tests before surgery are an important part of the preoperative evaluation process and can help identify potential risks and complications associated with the surgical procedure. By performing these tests, healthcare providers can ensure that patients are properly prepared for surgery, and can help ensure that the procedure is performed safely and effectively. If you are scheduled for surgery, it is important to follow your healthcare provider’s instructions regarding blood tests and any other preoperative evaluations that may be required or they are likely to cancel your surgery.
