Serum, NA, Fasting or Non Fasting: As suggested by doctor
A blood sample is required for the Cholinesterase (Pseudo), Serum test. This sample is usually collected from a vein in your arm using a needle.
The results of the Cholinesterase (Pseudo), Serum test are typically available within a few days, although the exact turnaround time may vary depending on the laboratory’s procedures.
Test Normal Range:
The normal range for Cholinesterase (Pseudo) in the serum can vary between laboratories. Your healthcare provider will interpret your results based on the reference range provided by the specific lab conducting the test.
What is the Test?
The Cholinesterase (Pseudo), Serum test measures the activity of an enzyme called pseudocholinesterase in your blood. Pseudocholinesterase is involved in breaking down certain drugs, including muscle relaxants and local anesthetics. This test is often used to assess a person’s sensitivity to these medications.
A healthcare provider will clean the area around a vein in your arm and use a needle to draw a blood sample into a vacuum-sealed tube. The blood sample will be labeled with your name, date of birth, and other identifying information. The blood sample is delivered to a lab for examination. The laboratory measures the activity of pseudocholinesterase in your blood and provides the results to your healthcare provider.
When to Take the Test:
The Cholinesterase (Pseudo), Serum test is typically performed before surgeries or medical procedures that require the use of muscle relaxants or local anesthetics. It can also be used to assess the risk of an adverse reaction to certain medications.
Who Should Take This Test:
Individuals who are scheduled for surgery, especially those involving muscle relaxants or local anesthetics, may be asked to take this test. Additionally, individuals who have a history of unusual reactions to specific medications may also undergo this test to assess their sensitivity.
Precautions for Exceptional Cases (Pregnancy, etc.):
There are usually no specific precautions for pregnant individuals or other exceptional cases when taking the Cholinesterase (Pseudo), Serum test. However, it’s essential to inform your healthcare provider about any underlying medical conditions, medications, or allergies before the test.
