easiTrace sampling info
How does the label work?
Blood is blotted (not excessively) on to the blotting-paper strip on the back of the adhesive easiTrace™ label. The blood and DNA become bound into the paper. The paper contains preservatives that allow the samples to be stored at room temperature.
How to sample
- Peel the easiTrace™ label from its backing
- Take a blood sample using one of the following methods:
- prick the ear with a lancet and drip a couple of drops of blood on to the paper strip
- wipe the paper strip on an area of animal/meat where blood is present
- Stick the easiTrace™ label on to the bar-coded ticket provided
- It is preferable not to collect samples in the rain
- Let the sample dry completely – do not let samples dry in direct sunlight
How much to blot

- The amount of blood on the second sample is perfect
- Saturating the sample with too much blood can lead to:
- cross-contamination from one sampler to another
- difficulty drying the blood sample
- poor blood preservation and inadequate DNA extraction
Avoid contamination
- Make sure that hands are clean of all blood before each sample is taken
- Clean lancet thoroughly between taking samples or use a new lancet for each sample
- Try not to let samples come into contact with each other until the samples have dried
What information is required?
- Correctly record on the bar-coded ticket
- Tag Identifier (BirthID/Herdbook ID/Registration No.)
- Sex
- Complete a submission form and ensure all essential animal information is provided
- For easiTrace™ sampling kits please contact the Genomnz™ laboratory.
Storage
- Allow the blood to dry and store the samples dry at room temperature
- Do not store in plastic bags because condensation can occur
- Correctly stored samples are stable for several years and can be sent for analysis as required
