Hi Everyone!
can i have one request that fetches multiple type of observation and to have only latest one per type
for example if i filter with code=http://loinc.org|29463-7,http://loinc.org|8302-2 (body weight and body height codes)
i get 2 entries one for latest body weight measurement and one for body height measurement

See the $lastn operation: http://hl7.org/fhir/observation-operation-lastn.html (caveat: probably not widely implemented)

thx @Michele Mottini
i am using cerner.com's api and it's not implemented there any other suggestions?

Not really. You have to get all observation, or use separate call (one per code) - if you know the codes you are interested in
