The white blood cell count is very high indicating an infection and is concerning. The platelet count is low but it can also vary based on how clean the blood collection method is as this can cause artifacts sometimes. If that is accurate and it correlates with the low HCT value, then it is very concerning as that can indicate an auto immune disease,a tick borne disease, or a blood disorder from a toxin such as rat poison. All of these causes are very serious and can have prolonged recoveries
