Diagnostics of maldigestion / malabsorption
For the examination from serum we need approx. 0.5 ml serum. For the examination from faeces we need a sample the size of a cherry and from urine 2ml are sufficient.  | Parameter |  | Material |  | Method |  | Species |  | Duration (days) |  | Remarks |  |
| | TLI (Trypsin-like Immunoreactivity) |  | serum |  | EIA |  | dog, cat |  | dog 2 cat 10 |  | - The animal must have been fasting for at least 12 hours.
- Substitution therapy does not interfere.
|  | | | |  | Vitamin B12 |  | serum |  | LIA |  | dog, cat |  | 1 |  | - decreased with „bacterial overgrowth“ and EPI
|  | | |
| | Folic acid
|  | serum |  | LIA |  | dog, cat |  | 1 |  | - increased with „bacterial overgrowth“ and EPI
- decreased: absorption disorders

| | Total fatty acids |  | faeces |  | spectro-graphic (NIRS) |  | dog, cat |  | 1 |  | - detection of disorders of fat digestion
|  | | | |
| | Bile acids |  | faeces |  | chemical-photo- metric |  | dog, cat |  | 1 |  | - increased with „bacterial overgrowth“
- disorders of fat absorption
|  | | | |  | Particle size |  | faeces |  | measuring |  | horse |  | 1 |  | - evidence of insufficient break-up
