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).
Do you need labs for 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 is Plavix monitored?
Most clinical studies on clopidogrel rely on
standard platelet aggregometry to measure inhibition of ADP-induced aggregation
(4)(5). In addition to aggregometry, cytometric determination of surface expression of platelet proteins, in particular P-selectin (CD62P), is commonly used to monitor platelet activation.
How do you test for clopidogrel?
The best assays to monitor clopidogrel therapy include
VerifyNow and Multiplate ADP test
.
What is clopidogrel resistance test?
Clopidogrel is a drug that is part of a group of medications called antiplatelet drugs and is used… This test helps determine if you may be less responsive to the drug clopidogrel because of your genetic makeup. This test
detects genetic variation in the gene CYP2C19
.
How do you know if Plavix is not working?
UNC
researchers developed testing to detect the genetic markers
for the 2 to 4 percent of patients who don’t respond to Plavix or others who are poor or intermediate responders. A current study tests all UNC patients prescribed the drug. It’s a simple blood test with results in one to two days.
How do you know if Plavix is working?
Talk to a pharmacist or your doctor before buying any over-the-counter medicine
to check if it is compatible with Plavix. You may notice that you bruise or bleed more easily and it will take longer to stop bleeding while you are taking Plavix. This shows that Plavix is working.
Does clopidogrel affect blood pressure?
You likely won’t have blood pressure changes while you’re taking Plavix
. However, sudden drops in blood pressure may be a symptom of serious internal bleeding, which is a possible side effect of Plavix.

When do you teach clopidogrel?
Take clopidogrel

5%–44%
.
What foods should I avoid while taking clopidogrel?
Is there any food or drink I need to avoid? Do not drink
grapefruit juice
while taking clopidogrel. Grapefruit juice decreases the effects of your medicine, so that it may not work as well to prevent clots.
What causes resistance to Plavix?
The two most common
CYP2C19 gene polymorphisms
associated with clopidogrel resistance (known as CYP2C19*2 and CYP2C19*3) result in the production of a nonfunctional CYP2C19 enzyme that cannot convert clopidogrel to its active form.
Does clopidogrel weaken immune system?
Clopidogrel may also
cause weak immunosuppression
that might contribute to risk of fatal infections (4).
