What is the blood test for Plavix?
Coagulation | Plavix VerifyNow Platelet Reactivity (PRU) Test. Test results are in P2Y12 reaction units (PRU). This test measures the extent of platelet aggregation in the presence of P2Y12 inhibitor drugs such as clopidogrel (Plavix), prasugrel (Effient), ticagrelor (Brilinta) and ticlopidine (Ticlid).
Does Plavix need monitoring?
Although the need to monitor clopidogrel efficacy has increased, no standard method is available at present. Most clinical studies on clopidogrel rely on standard platelet aggregometry to measure inhibition of ADP-induced aggregation (4)(5).
What is a normal P2Y12 level?
Onsite Collection (Michigan Medicine Hospitals Only): DO NOT SEND THROUGH PNEUMATIC TUBE SYSTEM. Collect specimen in a blue top (citrate 3.2%) tube using a 21 gauge or larger needle; do not use 1.8 mL tube. Mix by inversion. Send specimen to lab within 3 hours of collection.
How does P2Y12 test work?
The VerifyNow-P2Y12 Assay/VerifyNow PRU Test is a rapid test that uses ADP to stimulate platelets in the presence of PGE1 [Prostaglandin E1] and which inhibits activation downstream of a second ADP receptor P2Y1 – making the assay more sensitive and specific for the activity of the P2Y12 receptor and of drugs that bind …
Do you need blood tests with Plavix?
Clopidogrel doesn’t require regular blood test monitoring, but it affects platelet function and bleeding times for up to 7–10 days. You may need to avoid elective dental work and elective operations while taking aspirin or clopidogrel due to risks of bleeding.
How do you know if Plavix is working?

How common is Plavix resistance?

How do you monitor Plavix therapy?
The best assays to monitor clopidogrel therapy include VerifyNow and Multiplate ADP test.
What is a Verify Now test?
The Verify Now system is an FDA approved test to measure and quantitate platelet responsiveness to a variety of antiplatelet medications including aspirin or P2Y12 inhibitor drugs (e.g. clopidogrel, ticagrelor, prasugrel).
Which lab test result should you check before beginning the clopidogrel therapy?
Clopidogrel resistance testing is primarily ordered prior to having you take clopidogrel for the first time or during the initial treatment phase but may also be ordered when you are being treated with the drug and have experienced either excessive blood clotting or bleeding.
Can I take aspirin instead of Plavix?
Aspirin combined with the antiplatelet drug clopidogrel is no better than aspirin alone for stroke prevention in people with a history of lacunar strokes, and the combination carries a greater risk of gastrointestinal bleeding, according to results of a trial funded by the National Institutes of Health.
Why do some patients not respond to clopidogrel?
Some people with clopidogrel resistance have a reduced ability to convert the drug to its active form because of a polymorphism in one copy of the CYP2C19 gene that results in decreased enzyme activity. These individuals are described as intermediate metabolizers.
Does Plavix require blood work?
There are no blood tests required for plavix. It works later in the clotting mechanism and the inr would not reflect its effect. Plavix stops the blood from forming platelets and with out them the blood isn’t as thick as normal but it is not a blood thinner.
