Exceeding this deadline can result in erroneous analysis results – as also stated in the user’s manual, for the most widely used machine on the market
Advisor Ellen Møller Hansen from Unitron A/S, has shared her experiences with testing the influence of the time factor and has come to quite notable deviations from incorrect use of test equipment.
In the test, samples were taken which were analyzed immediately and after 30 minutes, respectively. The latter can occur, for example, if you collect samples and analyze them after the stable round is over.
The avarage hemoglobin level in the test of 14 piglets was 122 g/L in the immediate (and correctly performed) analysis. If the samples were allowed to rest for 30 minutes, two samples out of the 14 were extremely dispensing and the average result of the residues showed 108 g/l. A decline of just under 11.5%
Therefore, remember that the veterinarian, the consultant (or if you have purchased test equipment yourself) must analyze the samples taken max. 10 minutes after. Otherwise, you can sometimes misdiagnose and judge – in the worst case, believe that the piglets have anemia (that the blood content of the oxygen-carrying hemoglobin is not high enough), without it being the case.
