The Johnson Grass Allergy Test is a blood test that checks for an allergic response to Johnson grass, a common grass in the southern United States. It is ordered when a person has allergy symptoms such as sneezing, runny nose, or itchy eyes that may be related to grass pollen.
What it measures
- Johnson grass-specific IgE — The main marker; IgE is an antibody linked to allergic reactions.
- Total IgE — Sometimes measured to give a general sense of allergic tendency.
- Other grass-specific IgE — May be checked to see if you react to similar grasses like Bermuda or timothy.
Who it is for
This test is usually ordered by an allergist, primary care clinician, or other healthcare provider when a grass pollen allergy is suspected.
Preparation
No fasting or special preparation is needed for this blood test. You can eat and drink normally before your appointment.
Results and what they mean
Results are reported as a number or class that shows the level of Johnson grass-specific IgE in your blood. A clinician interprets these results along with your symptoms and history; a positive result alone does not confirm an allergy. This is general information and not medical advice.
