Key takeaways
- Needle phobia (trypanophobia), vasovagal fainting and difficult venous access are common reasons people delay important blood tests.
- Our Harley Street phlebotomists use ultrafine 23G and 25G butterfly needles, fully reclining clinical couches and topical anaesthetic options on request.
- Combining all required markers into a single venous draw means only one needle insertion for your entire check-up.
- You can book an appointment online at 117a Harley Street and let our reception team know in advance so we allow unhurried time.
Why some veins are harder to find
Small, deep or mobile veins, dehydration, cold weather, previous chemotherapy, frequent hospital cannulation or natural anatomy can make a standard blood draw uncomfortable when rushed. When a practitioner makes multiple unsuccessful attempts with a standard straight needle, both vein spasm and anxiety get worse.
At Blood London, phlebotomy is our dedicated daily practice. Our senior phlebotomists assess both arms, the back of the hand and warmth before choosing the finest appropriate gauge.
How we make your blood draw easier
- Ultrafine butterfly needles: winged infusion sets with flexible tubing reduce movement at the vein and allow gentle, low-vacuum collection into small paediatric or standard tubes.
- Reclining couches for fainting (vasovagal syncope): lying flat before the draw keeps blood pressure steady and prevents dizziness or fainting.
- Topical numbing options: local anaesthetic cream or spray can be applied ahead of the draw for severe needle anxiety.
- Warmth and hydration: warming the forearm and drinking plain water 30 to 60 minutes before arrival visibly improves vein filling.
Get every test done in a single draw
Because vacuum blood tubes clip onto the same butterfly adapter without removing the needle, taking four tubes feels the same as taking one. Your single £50 phlebotomy fee covers as many tests as you add to your basket, such as a Full Blood Count (£41.25), Ferritin (£68.75) and Vitamin D (25-OH) (£78.75), or an all-in Essential Full Body Blood Test (£329).

Frequently asked questions
Can I lie down before the needle is used?
Yes. Tell the phlebotomist as soon as you enter the room and you can lie flat on the couch before the tourniquet goes on and stay resting afterwards for as long as you need.
Can I drink water before a fasting blood test to help my veins?
Yes. Plain still water never breaks a medical fast and drinking two glasses of water in the hour before your appointment makes veins much easier to access.
Can I bring a partner or friend into the room?
Of course. A companion is always welcome to sit with you during your appointment at 117a Harley Street.
