What's this test for?

This test is ideal if you're currently being treated with vancomycin, an antibiotic used for serious bacterial infections like MRSA. It helps check whether the amount of medication in your blood right after a dose is at a level that works well without being too high. This is especially useful if you're being treated for a tough infection or can't take penicillin-type antibiotics.

What happens after I get my results?

Your vancomycin peak level will show up in your account along with the normal reference range so you can see exactly where your result falls. If your level is too high or too low, the report explains what that means, and retesting may be needed to adjust future dosing timing. You can download a standard lab report from your account at any time, and if you're on vancomycin for a while, the trends feature lets you track your levels across multiple tests.

Who should consider this test?

Anyone currently receiving vancomycin for a bacterial infection, especially by IV, should consider this test. It's particularly useful for people being treated for MRSA or other resistant infections, or those who can't use penicillin or cephalosporin antibiotics. It's also relevant if you have kidney concerns, since vancomycin levels can build up more easily when kidneys aren't clearing it efficiently.

What symptoms indicate I may need this test?
If you're on vancomycin and experiencing signs like ringing in your ears, dizziness, reduced urination, or a rash, checking your peak level can help figure out if your dose needs adjusting. Worsening infection symptoms despite treatment, such as continued fever or spreading redness, can also be a reason to check your levels. These signs don't always mean something is wrong, but testing helps clarify what's happening in your body.
When will I get my results?
Results for this test are typically ready within about 7 days of your blood draw. Because vancomycin peak timing is important, your blood is drawn at a specific point after your dose, and the lab processes it fairly quickly given the medical nature of the test. You'll see your results posted directly to your account as soon as they're finalized.
How can I naturally support healthy kidney and infection recovery?
While vancomycin dosing itself needs to be professionally managed, you can support your body's ability to process the medication by staying well hydrated unless you've been told to limit fluids. Eating a balanced diet with adequate protein can help your body recover from infection. Avoiding other substances that stress your kidneys, like excess NSAIDs or alcohol, while on antibiotic treatment is also a good idea.
What does a high vancomycin peak level mean?
A high peak level means there's more of the drug in your blood than the target range, which can increase the risk of side effects like hearing changes or kidney stress. This usually means the dose or timing needs to be adjusted going forward. If your result is very high or you're having symptoms like ringing ears or reduced urination, seek medical care right away.
What does a low vancomycin peak level mean?
A low peak level means there may not be enough medication in your blood to effectively fight the infection. This could mean the dose needs to be increased or given more frequently so the antibiotic can do its job. It's important to keep taking the medication as directed and get retested to confirm the level after any adjustment.
What causes an abnormal vancomycin level?
Levels can run high if your kidneys aren't clearing the drug efficiently, if the dose is too large, or if the blood was drawn at the wrong time relative to your dose. Low levels are often caused by the dose being too small, taking longer infusion breaks than expected, or drawing blood too soon after the infusion. Body weight, hydration status, and overall kidney function all play a role too.
How often should I retest my vancomycin levels?
Retesting frequency depends on how long you're on the medication and how your first results look. If your levels are on target, retesting every few doses or as instructed on your order confirmation is common. If levels are outside the target range, more frequent monitoring is typically needed until things stabilize.

Vancomycin, Peak 32 mcg/mL
Demo results
Low (<20 mcg/mL) Optimal (20-40 mcg/mL) High (>40 mcg/mL)

A peak level of 32 mcg/mL falls within the optimal treatment range for most infections. This suggests the current vancomycin dose is providing an effective concentration to fight the infection without being excessively high.
