| Description | Quantitation of nitrates by colorimetric method. The half-life of nitrates in beef cattle exposed to nitrates is between 7.7 to 9 hours. Therefore, it would be at least five biologic half-lives (24–36 hours) before increased nitrate concentrations from excessive nitrate exposure diminish to normally expected values, which means that affected cattle should be tested preferably within 24 hours after a significant nitrate exposure. |

| Additional Instructions | As soon as possible, remove serum from blood tube and store at refrigeration or preferably freezer temperature and ship to the lab on ice packs. If possible, remove clear ocular fluid from globe and keep at refrigeration or freezer temperature prior to shipping and ship on ice pack. If globe submitted, keep at refrigeration temperature and ship on ice packs as soon as possible to the lab. See our Resources page for proper sampling instructions for nitrate in feedstuffs. |
