When and how often laboratory tests are done may depend on many factors. The timing of laboratory tests may rely on the results or completion of other tests, procedures, or treatments. Lab tests may be performed immediately in an emergency, or tests may be delayed as a condition is treated or monitored. A test may be suggested or become necessary when certain signs or symptoms appear.
Due to changes in the way your body naturally functions through the course of a day, lab tests may need to be performed at a certain time of day. If you have prepared for a test by changing your food or fluid intake, lab tests may be timed in accordance with those changes. Timing of tests may be based on increased and decreased levels of medications, drugs or other substances in the body.
The age or gender of the person being tested may affect when and how often a lab test is required. Chronic or progressive conditions may need ongoing monitoring through the use of lab tests. Conditions that worsen and improve may also need frequent monitoring. Certain tests may be repeated to obtain a series of results, or tests may need to be repeated to confirm or disprove results. Timing and frequency of lab tests may vary if they are performed for professional or legal reasons.
Before a wound culture, you may be offered medication for pain. You will need to have your body in a position to allow the healthcare worker access to the wound.
A wound culture sample may be made up of cells, tissue, or fluid. Methods used to obtain a wound culture vary depending on many factors, including the location and type of wound. Before the procedure, the healthcare worker will usually clean the area with antiseptic solution, and place sterile cloth around the wound. To collect a sample from certain wounds, the healthcare worker will press or squeeze near or on the wound and use a sterile swab to gather fluid, cells, or tissue. The swab may also be inserted deeply into the wound and rotated to collect a sample. For a deep wound, a needle and syringe may be used to draw material from the base of the wound for the sample.
The amount of discomfort you feel will depend on many factors, including your sensitivity to pain. Communicate how you are feeling with the person doing the procedure. Inform the person doing the procedure if you feel that you cannot continue with the procedure.
After a wound culture, follow the healthcare worker’s instructions regarding taking care of the wound. Call your healthcare worker if you have increasing pain, redness, swelling, discharge or bleeding from the wound. Inform them if you develop a fever, start vomiting, or have increasing fatigue.
