Exams and Tests
Your doctor can usually diagnose
mastitis based on your symptoms and an examination of
the affected breast
. Tests are usually not needed. But
they may be done to confirm a diagnosis or to help guide treatment for other
problems that can develop.
Breast milk culture
If you have an infection that
isn't improving with treatment, your doctor may do a breast milk
culture. To provide a sample for a culture, you will
squeeze a small sample of milk from the affected breast onto a sterile swab.
The culture results help your doctor confirm a diagnosis and to find out the
specific bacteria that are causing the infection.
In some cases, it
takes more than one round of antibiotics to clear a breast infection. If you
have not been responding to antibiotic treatment, culture results may be used
to find out the most effective antibiotic for you.
Abscess
Sometimes a pocket of pus (abscess) forms
in the reddened area of the breast. If an abscess is too deep to examine by
touching it, your doctor may use a
breast ultrasound to examine it. Ultrasound can also
be used to guide a needle to an abscess that needs to be drained of fluid. A
culture of the abscess fluid is usually done to identify the infecting
organism.
