Final answer:
Yes, hematocrit level can be obtained from a single drop of blood using miniaturized technologies like 'lab-on-a-chip'.
Step-by-step explanation:
Yes, it is possible to obtain a hematocrit level from a single drop of blood using miniaturized technologies. One such technology is the 'lab-on-a-chip' developed by researchers at Columbia University. This technology tests a single drop of blood and can measure various parameters including hematocrit level. The blood is pulled through tiny capillaries into reaction chambers where the analysis takes place.
