I need help on how to save this as a .dat file. When I do
save bloodinfo.dat
and then do
type bloodinfo
it is not there.
How can I save this file?

Your example looks like the content of a text file. Is it? Inside Matlab this "info" may be stored in a cell array or maybe a table. How is it stored?
"do save bloodinfo.dat" Exactly how did you do that?

Original question below, in case he deletes this one also, like he has before in other threads:

Try this
fid = fopen('bloodinfo.dat', 'wt');
for k = 1 : length(value1)
fprintf(fid, '%s, %s, %d, %d\n', patientName{k}, bloodtype{k}, value1(k), value2(k))
end
fclose(fid);
type('bloodinfo.dat');
Obviously replace the variables with whatever your variables are named.
