Answer:

One of the major limitations of capillary blood sampling is the potential for errors in the collection of blood samples. If the puncture is too deep or if the finger is squeezed too hard, this can result in a contaminated blood sample that may not accurately reflect the true metabolite concentrations in the blood.

Another factor that can affect the accuracy of equipment used to measure metabolite concentrations in capillary blood is the quality of the equipment itself. The accuracy and precision of glucose meters and other measuring devices can vary widely depending on the make and model of the device, as well as its age and condition.

Other factors that can affect the accuracy of capillary blood testing include temperature, humidity, and altitude. These factors can affect the stability of metabolites in the blood, as well as the accuracy of the measuring equipment.
