The milk should be checked in all cases when the cow was treated because antibiotic residue could remain in the milk for some time. Such milk is not suitable for consumption and processing. With the help of milk testing by Delvotest® you will know how long the drug residue remains in the body and how long they could be detected in the milk. Check the milk, especially if:
1. Health condition of treated cow was very poor or she is suffering from dehydration.
2. The drug was used not according directions (higher doses, injections made to other places, milky cow gets preparations for dry cow), therefore the exact time of medicine residue elimination from the body is not known.
3. The drug was injected at a point where the blood circulates poorly, for example at a layer of scar formed after the previous injections.
4. The drug or mixed drug was given in combination with another medicine.
5. Dry period was short.
6. A cow was treated by antibiotics, calving started too early.
7. The cow was treated for a specific disease within dry period.
8. The cow was dried in one quarter of udder, for example when the teat was damaged.
9. There is a new cow in the herd.
DSM‘s Delvotest® microbial test detects the widest range of antibiotic residues with a single easy-to-use test. It is a true helping hand for Farmers who test at individual cow level by making sure the bulk tank is always free from antibiotic residues. Delvotest® is extensively used at Dairies and Milk Control Laboratories and has become the national reference test in most countries worldwide due to its consistency, reliability, accuracy and performance.

Delvotest® Fast Q
This test is an innovative, one-step, rapid qualitative test for the detection of β-lactams, tetracyclines, sulfonamide and quinolone residues within a few minutes in raw cow milk.
Delvotest® Fast BT
This test is an innovative, one-step, rapid qualitative test for the detection of β-lactam and tetracyclines residues within a few minutes in raw cows, goats and sheep milk.
Delvotest® Fast Q and Delvotest® Fast BT – are based on rapid immunochromatographic technology to qualitatively detect antibiotic residues in raw milk. Using these tests offers reliable test readings with Delvotest® Fast Go Max reader, that provides a quantitative assessment and enabling real-time result sharing and full traceability.
Delvotest® SP NT microbial tests, detecting the broadest spectrum of antibiotic residues in every kind of milk – cow, sheep, goat,buffalo – as well as in dairy products.
It is long method - about 2,5 hours.
Delvotest® T is standard diffusion for anti-bacterial agents such as antibiotics and sulfanomides residues in milk to detect. The duration of analysis is about 3 h and 15 min.
Instruction for Delvotest® T plates:
Delvotest® Fast Start III Incubator with integrated thermometer and timer functions has been developed for incubating Delvotest® Fast BT and Delvotest® Fast Q antibiotic residue test cassettes.
Delvotest® Fast Go Max – is a reader specifically designed to be used with Delvotest® Fast BT and Delvotest® Fast Q cassette tests for the detection of antibiotic residues in milk, that gives quantitative assessment and ensures traceability, as the data is automatically stored on the device.
Delvotest® Incubator - for Delvotest® T / Delvotest® SP-NT ampoules heating.
Delvo® Scan was developed to offer the possibility to read Delvotest excluding the influence of the human factor. Delvo® Scan provides a fully automated option for reading and documenting tests results of Delvotest® plates as well as ampoules. What’s more, our software saves the results in a standard format so that they can easily be imported into data management systems.
Delvotest® Accelerator - innovation in milk testing. Fully automated and cost-effective, allowing dairies and milk control stations to investigate the contamination of antibiotics. Benefits - a wide range of research, reliable and convenient to use.
Delvotest® Negative Control - it is reference milk sample without antibiotics residues or Delvotest Negative Control, can be used for tests control and as negative milk control sample in determing correct Delvotest® SP NT and Delvotest® T test duration, also the antibiotic and antimicrobials residues in milk check.
Delvotest® Pen 4 Control - DSM Food Specialties milk control sample Delvotest® Pen 4 Control is dried, mixed cow milk. It can be used as monitoring for antibiotics residues in milk detecting tests, which are used in dairy industry. This control can be used for Delvotest® and other systems.
