VEI Check · Blood & Lab

Choosing only what you need
to check where your body is now

At VEI Clinic, blood and urine testing starts with an internal medicine specialist listening to your symptoms and the reason for testing, then choosing the relevant items. Rather than running many tests at once, we decide what needs checking now and use it to set a care plan.

FAQ

Frequently asked questions

Do I need to fast?

It depends on the tests. If an item such as a lipid test requires fasting, we will tell you in advance how many hours to fast.

Can you test exactly the items I want?

We first hear why you want testing and decide on medically appropriate items together. If items need to be adjusted, we explain why and get your consent before proceeding.

Can I be tested with an order from another clinic?

In most cases, yes. Bring the order and we will help with the blood draw and testing, and compare with any previous results you have.

I am very afraid of needles. Will I be okay?

We can use numbing spray, draw with you lying down and take breaks along the way. Just tell us what feels comfortable.
