You would not need blood, a cheek swab will work for most testing companies.

If the Scot versus Ukrainian alternatives are on his father's paternal line,
then there is a good chance a y-dna test will be able to say something to
clarify the possibilities.

Ukrainian y-dna is heavily of a type (a haplogroup) called R1a which has
some unique identifying markers. Scot y-dna is heavily of another type,
R1b.
Secondarily, Ukrainian y-dna is of a type called Dinaric I1b, while the
secondary types found in Scotland are I1a and I1c. Each type has markers
which allow it to be distinguished from the others. So he stands a good
chance of tilting the odds one way or the other between Scot versus
Ukrainian.

Things are not fool-proof, however. A tiny number of R1b folks and I1a
migrated for one reason or the other to Ukraine, while the Scandinavians who
came to Scotland 1000+ years ago brought a little R1a with them, and
Scandinavian R1a often looks somewhat like Ukrainian R1a (though
statistically they are different). However, even in these cases one can
sometimes see differences within the groups which suggest geographical place
of origin.

There are public databases to compare ydna haplotypes, and people on this
list have organized the haplotypes from various regions and from the various
genetic groups, so that identification of which a particular haplotype
"belongs" to is made easier.

If he is trying to find his mother's maternal line ethnic background with
help of mt-dna, then the task is more difficult. This maternal line mt-dna
mutates much slower; and for reasons not yet understood, the groups found
within mt-dna are more mixed up and dispersed in Europe than is the male
y-dna. It is more difficult to definately associate a mt-dna group with a
particular geographical area, though some connections have been discovered.
