Med Tech students from Louisiana State University Alexandria(USA) and Med Tech students from National Public Health Laboratory in Kenya (Africa) will analyze and compute Reference Ranges for Hematology Test Parameters and compare ranges between both countries. Students will also communicate through this blog site to develop understanding and appreciation for different cultures.

Cathy:
Before you begin running specimens to use in determining your Reference Range You need to look up the requlations and see 'whose' blood you can use. List information you found researching this topic here.
Meghan:
Reference ranges can be determined for ill and healthy individuals.
When reference intervals are established there are five factors that should be followed.
1. Makeup of the reference population with respect to age, sex, and genetic and socioeconomic factors;
2. The criteria used for including or excluding individuals from the reference sample group;
3. The physiologic and environmental conditions by which the population was studied and sampled, including time and date of collection, intake of food and drugs, posture, smoking, degree of obesity, and stage of menstrual cycle;
4. The specimen-collection procedure, including preparation of the individual; and
5. The analytic method used, including details of its precision and accuracy.
Julie,
This site gives really great information on reference ranges in many aspects of the lab. These ranges are what we go by in America. What are your reference ranges or how do they differ from ours?

Sylvia:
Has anybody found the regulations on how many individuals are need in each age group to get the Reference Range?
Cora:
Sylivia has a good question. I am currently researching that and have yet to find information with good background. Maybe I'm looking in the wrong places?
SAL:
I do agree with all of you about the things we need to consider for the project to be a success.
In addition to Meghan's points,we also need to state our hypothesis.That is;do we expect the reference ranges to vary with the five factors Meghan stated or even more?Im trying to come up with that.
With Sylvias's concern,I believe as long as you are not biased during sampling,your sample representation should be a reflection of the general population.
Iam also trying to research on how best we can do the project in terms of retrogressive or progressive approach.
Hope you will post your information as soon as you get any.
After much research and consulting, here are the qualifications for the participants we can draw blood specimens from:
1. 10 female and 10 male volunteers between 17 and 60 years old.
2. 'Generally considered healthy' with no acute or chronic disease process
3. volunteers should not be on iron meds, or procrit, or have any type of blood (RBC, WBC, Plt) disorder.
4. Whole blood collected in an EDTA (lavendar top) from each volunteer first thing in the morning and run on automated instrument with in 1 hour of drawing specimen.
5. record control and patient results in a chart (excel) to be analyzed and compared.
6. Record: white blood cell count; red blood cell count; platelet count; hemoglobulin; hemacrocrit; the differential
(note whether diff is manual or recorded from instrument).
Sylvia:
Hello,I hope everthing is getting back to normal and you are able to get back to school/work. Have you been able to start working on the reference ranges yet? I along with Laura are doing a poster on our project and need any information you can give us on what was been done from your end.
