Diagnosis

A diagnosis of a bug bite rash requires a medical doctor to evaluate the rash in person.

A doctor may request a biopsy to confirm the diagnosis. This can be done with a skin biopsy in the office or with a skin blood test.

To perform the skin biopsy, a doctor will apply a local anesthetic to the area and then extract a small sample of skin (or skin blood test).

In the case of a skin blood test, a doctor will draw a small amount of blood from the patient’s arm and then send the sample to a lab for analysis.

The doctor may also order a test to determine the specific species of bug that bit you. The bug bite test can be performed in the doctor’s office or at a nearby lab.

The bug bite test involves a blood sample being taken from a vein in your arm. It is then sent to a lab for testing.

Results

The result of the bug bite test will determine what type of test you need to get.

If a doctor identifies a specific bug that bit you, they will likely order a blood test to determine if you have an allergic reaction to it.

If you do not have an allergic reaction but have a rash, the doctor may order a skin biopsy to rule out a bite that was infected with a parasite or worm.

If the doctor suspects that you have an allergic reaction, they may want to perform a skin biopsy to determine if it is a true bug bite.

If a doctor suspects that you have a bite that was infected with a parasite or worm, the doctor will likely order a skin biopsy to determine if you have a parasite or worm infection.
