Phlebotomy, the act of drawing blood, is essentially used to analyze and diagnose a patient’s condition. It includes profoundly developed, thoroughly tested techniques and needles that guarantee the security and solace of the patient and the uprightness of the gathered samples.
For your convenience, Yourhealthfirst offers a ‘walk-in’ service. However, patients are advised to book an appointment as patients of our clinic are given priority. Waiting times during clinical hours can reach up to 45 minutes or more if appointment is not booked.
If you must fast before your blood test, please ensure you have fasted for 12 hours prior to your test. You may sip small amounts of water and take any necessary medications.
