I always wondered what difference not having exactly 10ml makes on the test. For instance how much does it affect the results if I have +\-1-2 ml difference? I think it’s arbitrary where u call 10ml. Is it at the bottom of the meniscus? I think this would also affect if this is truly 10ml..

Bottom of the miniscus should align with the 10 ml line.

The volume of sample +/- around the 10 ml will change the FC result the same %.
