Could antibiotics affect the numbers on my blood test before my tummy tuck?

Question

I am currently taking a 14 day antibiotic regimen for HPylori. I am having labs drawn in a few days and would like to know if the antibiotics is going to affect the numbers on my blood test? The main ones I'm worried about being affected is the hemoglobin number and then the PTT and PT with INR. These numbers are the main ones my plastic surgeon will be requesting. Thanks

Thank you for your question regarding antibiotics and your upcoming blood tests. Antibiotics, including those used for treating H. Pylori, typically don’t have a direct effect on hemoglobin, PTT (partial thromboplastin time), PT (prothrombin time), or INR (international normalized ratio) levels. These tests primarily assess your blood’s clotting ability and your red blood cell levels, neither of which are generally influenced by antibiotics.

However, some antibiotics can occasionally impact the liver or kidney, which could indirectly influence clotting factors in rare cases. If you've had any recent changes in energy levels, appetite, or signs of gastrointestinal discomfort, it might be a good idea to mention this to your healthcare provider as they interpret your results. If you have any remaining concerns, your plastic surgeon or primary care physician may provide additional guidance.

In general, though, you should be able to proceed with confidence that your antibiotics will not impact these specific lab results significantly.

Sincerely,
Dr. Katzen

I encourage you to speak to your surgeon about the antibiotic course you are currently taking and the reason behind it.  Your surgeon can then advise you about continuing with the planned preoperative labs.  It is important that your surgeon is aware of all medications that you take including prescription, over the counter, and supplements.

No, antibioitics will not affect your red blood cells counts or how well your blood coagulates. However, your white count can be affected and usually is improved.

Antibiotics have the potential to impact the outcomes of specific blood tests before undergoing a tummy tuck surgery. These medications can have an influence on various parameters, such as the count of white blood cells or the levels of liver enzymes. These parameters are usually evaluated through pre-operative blood tests. It is crucial to communicate with your healthcare provider regarding any medications you are currently taking, including antibiotics, prior to any medical procedures.
