Labmaster LUCIA™ Veterinary Diagnostics

Labmaster Foal IgG Test

The Labmaster LUCIA™ Foal IgG Kit

for Whole Blood Samples

This quantitative rapid test is intended for measuring IgG antibody levels in newborn foals as an aid in assessing failure of passive transfer of immunity (FPT, FTPI). The test can easily be performed at the stable and it produces a numerical result in 6 minutes. 

Test description

The Labmaster LUCIA™ Foal IgG test is an in vitro veterinary diagnostic test for the quantitative determination of determination of Immunoglobulin G (IgG) from foal whole blood to assess failure of transfer of passive immunity (FTPI).

The Labmaster LUCIA™ Foal IgG Kit is to be used with the semi-automated Labmaster LUCIA™ Vet Analyzer.

About the analyte

Newborn foals are entirely dependent on antibodies absorbed following ingestion of mare’s  colostrum for protection against infectious diseases. After 24 hours a foal is considered to have failure of transfer of passive immunity (FTPI), if circulating immunoglobulin levels are less than 400 mg/dl. FTPI occurs in 10 to 20% of newborn foals (i). It is the most common immunodeficiency disorder in horses and associated with an increased risk of infectious disease and mortality, which is why routine monitoring is recommended, to allow early detection and treatment (ii).

I recommend testing of IgG levels for all foals. The level of the foal’s antibodies cannot be deduced from the foal’s external appearance!
I use a Labmaster LUCIA™ VET analyzer with which I get a quantitative result of IgG levels. The quantitative i.e. numerical result is particularly useful when the antibody levels are in the range of 400-800 mg/dL, in which case the exact result helps to make a decision about the necessity of plasma on a case-by-case basis.
Veterinarian Susanna Häkkä, “VetSuski"
Yes! It has arrived! Namely, the Labmaster LUCIA™ Vet Analyzer. We are able to study the SAA value of the horses here at the home stable and also measure the IgG of the foals.

Both of these results can be obtained numerically. This is valuable information which we don’t have to wait for long. anymore. Very important information, especially during foaling season.
