Why Are Pre-Operative Blood Tests Necessary?

Before undergoing any surgery, it is crucial to assess your overall health and identify any underlying medical conditions that could affect your procedure, its outcome, or your recovery.

preparing for appointment

Preparing for test

To prepare for a pre-operative blood test, consider the following steps:

  1. Follow Fasting Instructions: In some cases, you may be required to fast for a certain period before the blood test. This typically involves abstaining from food and beverages, except water, for a specific duration, usually 8 to 12 hours before your test.
  2. Stay Hydrated: Drink plenty of water before your blood test unless instructed otherwise by your healthcare provider. Staying hydrated can make it easier for the phlebotomist to locate your veins to collect your blood sample.
  3. Review Medication Instructions: Inform your healthcare provider about any medications, supplements, or herbal remedies you are currently taking, as some medications may need to be temporarily stopped or adjusted before your blood test.
  4. Dress Comfortably: Wear loose-fitting clothing with sleeves that can be easily rolled up to allow access to your arms for blood collection. This will make the process more comfortable for you and the phlebotomist.
  5. Stay Calm: If you feel anxious or nervous about your blood test, try to relax. Deep breathing exercises or listening to calming music can help alleviate anxiety. Inform the phlebotomist if you have a fear of needles or if you have experienced fainting or dizziness during blood draws in the past.
  6. Bring Necessary Documents: Bring any required documents, such as your identification card, insurance information, or pre-operative paperwork, to your appointment. This will ensure a smooth check-in process and help expedite the blood test procedure.
  7. Communicate Any Concerns: If you have any questions or concerns about the blood test, don’t hesitate to communicate them with your healthcare provider or the phlebotomist. They can provide additional information and address any worries you may have.

during the appointment

During the test

Depending on your medical history and the type of surgery you will undergo, you may need to undergo various laboratory tests, such as blood tests, urine tests, and resting ECGs to assess your organ function and overall health.

Overall, the pre-operative assessment is designed to ensure that you are medically optimised for surgery, minimise the risk of complications, and provide you with the necessary information and support to undergo a successful surgical procedure.

Results

Some of your results can be available as early as 12 hours after being sent to the lab. We will contact you as soon as all the information is ready.

As an international visitor, I was very grateful for the prompt attention to my request for an appointment. Dr Ali was respectful and empathetic in regard to my condition and suggested further treatment, which I was able to organise for the next day. Both offices I attended treated me appropriately and I would recommend Harley Street Health Walk-in Clinics to anyone visiting London who requires medical attention.

Highly recommend City Walk-In Clinic Really pleased with my experience at City Walk-In Clinic. I booked a female hormone test because I wanted some answers about a few symptoms I'd been having, and the whole process was straightforward. The staff were welcoming, friendly and didn't make me feel rushed at all. The blood test was quick, and they explained everything clearly before taking the sample. My results came back sooner than I expected, and it was reassuring to have everything presented in a way that was easy to understand. I'd definitely use the clinic again and would recommend it to anyone looking for a private female hormone test. Professional service, lovely staff and an all round positive experience.

I had a private gp appointment yesterday as my feet have been swelling every day over the past few days. So I booked an appointment with Dr Heather. Dr Heather explained the possible causes of the swelling, including the heat that we are currently experiencing in London. Recommended further investigation if the swelling persists, to identify the underlying issue rather than just making assumptions.

I have used City Walk In Clinic as my go to place for routine blood tests. My recent full health check gave my doctor some clues that i may be approaching my menopause era. So my doctor has recommended that i do some tests to find out if indeed i am entering perimenopause, as the symptoms are there. Will be having my tests in the next few weeks. So glad i had a full health check, because all these symptoms were driving me crazy.

I attended The Harley Street Walk/in centre in the City recently. I was able to book my appointment the day before for a blood test at a time that suited me. The booking process was straightforward. The doctor that conducted the venous draw was efficient and very pleasant. I have never had such a painless venous draw and I have had many! My appointment was at 5pm and I had my results before 8 am the following day. I will be very happy to book my tests here in the future. Thank you.

I wanted a cholesterol check up and chose this clinic because it seemed to offer a competitive price for a detailed report. And so it turned out to be. Received a prompt and professional service at a price that was significantly less than other nearby providers in central London. I have now used it twice and would definitely recommend.

The Walk-In Clinic in central London exceeded my expectations in every way. Their attention to detail and commitment to tailored care for their patients truly sets them apart. The availability of evening appointments until 6:30 pm was a game-changer for someone like me juggling multiple commitments.

Can I have a pre-operative blood test done without a referral?
Yes, we allow patients to book pre-operative blood tests without a referral, especially if you are preparing for elective or private surgery. However, if your surgeon or hospital requires specific tests, it is helpful to bring any referral forms or test requests with you.

How many days before surgery is pre op?

What happens if my pre-operative blood test results are abnormal?
If your blood test results reveal abnormalities, such as low haemoglobin, abnormal liver function, or clotting issues, your surgical team will be informed promptly. Depending on the findings, you may need further investigations, treatment, or adjustments to your surgery or anaesthetic plan to ensure your safety.
