My brother is healthy and had a routine blood test. page said sample was unfit for testing and came back with lots of zero values. what does this mean?

Lab draw error: Possibly there was a problem drawing your brother's blood, or the sample deteriorated before it could be tested. Sounds like he'll need to have another lab stick so measurements can be made.

Need to repeat tests: Don't worry, when blood is drown , placed into test tube, some times lacks enough preservatives so the blood clots inside the test tube and test could not be done , that is what happned to your brother's blood , need to send properly preserved blood to the lab.

Collection error: Something went wrong in collecting or transporting the specimen. It's not an indicator of a health problem for your brother.
