Frequently Asked Questions

What is the Viscosity Serum Test?
The Viscosity Serum Test measures the thickness of the serum (liquid part of blood) to help detect conditions like hyperviscosity syndrome, high blood pressure, heart disease, and diabetes.
Why is the Viscosity Serum Test done?
It is done to evaluate symptoms like unexplained bleeding, visual disturbances, dizziness, or confusion, and to monitor patients with conditions such as Waldenström's macroglobulinemia and multiple myeloma.
What does high serum viscosity mean?
High serum viscosity indicates thickened blood, which can reduce blood flow and may suggest hyperviscosity syndrome. It requires further investigation to determine the underlying cause.
How is the test performed?
A small blood sample is drawn from a vein in your arm. The sample is sent to the laboratory where a kinetic viscometer measures the serum viscosity.
Is fasting required for the test?
No, fasting is not required for the Viscosity Serum Test. However, a duly filled Test Send Out Consent Form (Form 35) is mandatory.
What is the normal range of serum viscosity?
The normal viscosity of serum typically ranges from 3.0 to 4.5 centipoise (cP). Values above 4.5 cP are considered elevated.
How much does the Viscosity Serum Test cost?
The test costs INR 10,000 at DNA Labs India. Free home sample collection is included with online booking.
How long does it take to get reports?
Reports are typically available within 2-3 weeks after the sample is received by the laboratory.
