What is VWF RCo?
The Von Willebrand Ristocetin Cofactor [vWF:RCo] assay measures the ability of a plasma sample to agglutinate platelets in the presence of the antibiotic Ristocetin. The rate of Ristocetin induced agglutination is related to the concentration and functional activity of the plasma von Willebrand factor.
What is the normal range for von Willebrand factor antigen?
In the general population, the mean level of plasma VWF is 100 IU per dL, with a normal reference range between 50 and 200 IU per dL.
What are the 3 types of von Willebrand disease?
Types of von Willebrand disease
- type 1 – the mildest and most common type. People with type 1 VWD have a reduced level of von Willebrand factor in their blood.
- type 2 – in people with this type of VWD, von Willebrand factor does not work properly.
- type 3 – the most severe and rarest type.
What does it mean when von Willebrand factor is high?
Background and Purpose— Elevated von Willebrand factor (vWF) concentrations are associated with an increased risk of ischemic heart disease.
How do you diagnose von Willebrand’s disease?
Diagnostic Tests
The blood tests that a doctor can order to diagnose VWD (or another platelet disorder) include: Factor VIII clotting activity―To measure the amount of factor VIII in the blood. Von Willebrand factor antigen―To measure the amount of VWF in the blood.
What is VWF collagen binding assay?
The collagen binding assay [VWF:CB] measures the binding of VWF to collagen and preferentially the High Molecular Weight [HMW] multimers of VWF and is therefore sensitive to VWD variants characterised by the absence of the larger VWF multimers.
How is von Willebrand disease diagnosed?
How is von Willebrand disease treated?
Desmopressin. This medication is available as an injection (DDAVP). It’s a synthetic hormone that controls bleeding by stimulating your body to release more of the von Willebrand factor stored in the lining of your blood vessels. Many doctors consider DDAVP the first treatment for managing von Willebrand disease.
What happens if you have von Willebrand disease?
If you have von Willebrand disease, you might have: Excessive bleeding from an injury or after surgery or dental work. Frequent nosebleeds that don’t stop within 10 minutes. Heavy or long menstrual bleeding.

Does von Willebrand make you tired?
Can you get the Covid vaccine if you have von Willebrand?
Patients with bleeding disorders can safely receive a COVID-19 vaccination if they follow the guidance below: If you have hemophilia or severe von Willebrand disease where your factor activity levels are less than 10%, treatment to raise your factor activity to greater than 10% prior to your vaccination is recommended.
Is von Willebrand disease considered a disability?
The condition is medically equal to a condition in the Listing of Impairments. If someone can prove that his or her von Willebrand disease is medically equal to any listing in the Listing of Impairments then that person may qualify for Social Security disability.
Can someone with von Willebrand disease get the Covid vaccine?
Does von Willebrand disease affect pregnancy?
Women with VWD are at risk for serious bleeding after delivery. During any pregnancy, the body makes higher amounts of clotting factors to prevent bleeding. However, the high levels of clotting factors during pregnancy drop back to lower levels after delivery.
How do you test for von Willebrand disease?
Can I get vaccinated if I have low platelets?
A current diagnosis or history of immune thrombocytopenia (ITP) is not a contraindication to receiving the COVID-19 vaccine, as long as your platelet count is above 20,000 (see below).
Can someone with von Willebrand have a baby?
Pregnancy and Childbirth
With proper care, women with von Willebrand disease (VWD) can have a successful pregnancy and deliver a healthy child. A woman who has VWD should be monitored closely throughout her pregnancy by her doctors.

76% of men with VWD had been diagnosed by age 10, but 50% of women with VWD were not diagnosed until after age 12.
How can I raise my platelet count fast?
How to Increase Platelet Count:
- Milk. We all know that milk is a rich source of calcium and protein and is important in maintaining the strength of bones and muscles in our body.
- Green Leafy Vegetables:
- Papaya Leaf Extract:
- Pomegranate:
- Pumpkin:
- Wheatgrass:

What foods to avoid if you have low platelets?
What Not to Eat
