What is the purpose of test?

To monitor udder health and as an early indicator of mastitis.

What is the LDH?

Lactate dehydrogenase (LDH) is an enzyme found in almost all body tissues.

Why you need to check LDH level?

LDH levels often rise earlier than somatic cell counts, making it an excellent marker for early detection of udder infections.

Result Interpretation


If the test strip indicates that the probability of infection is (-), then you need not do anything.

A (+)LDH indication will require future monitoring to ensure a reduction in the infection status.
You may want to sample again in a week time.

A (++)or (+++)LDH result indicates you have a (++)or (+++)probability of infection in the udder. It is recommended that you culture the (++)/(+++)quarters for infective pathogens.
Isolating the pathogen causing the infection allows you to work with your veterinarian to target appropriate antibiotic therapy.
