normal values

Also found in: Dictionary, Thesaurus, Legal, Financial, Encyclopedia.

nor·mal val·ues

a set of laboratory test values used to characterize apparently healthy people; now replaced by reference values.

chemistry, normal values

the amounts of various substances in the normal human body, determined by testing a large sample of people presumed to be healthy. Normal values are expressed in ranges of numbers, and ranges vary for different age groups and from laboratory to laboratory. For example, a normal concentration of a substance in the blood might be expressed as 5 to 20 mg/dL. Although variations from normal values may be highly significant tools in the diagnoses of certain diseases, in all cases an abnormal result must be cautiously interpreted. See also specific tests.

Patient discussion about normal values

Q. what is the normal range for young children for their sugarI tested my grandson the other day with my meter and it read 164?

A. Of course, if you have any suspicions or worries, you may want to consult a doctor (e.g. pediatricain)

Q. My Iron/TIBC tests normal, Ferritin,Serum = 22. Range 22-322. What is the problem? Iron Bind. Cap. ug/dL 324 range 250 - 450 UIBC ug/dL 206 range 150 - 375 Iron, Serum ug/dL 118 range 40 - 155 Iron Saturation % 36 range 15 - 55 Biopsy = Prostate Cancer....PCA high = 10.2 PSA now 8.3 PSA Ultra W/Serial Monitor ...Ultrasenitive = 8.26

A. What makes you think something is not normal? Ferritin values may be low in some people, and iron deficiency is usually defined as ferritin 15. Do you have anemia? Currently, it doesn't seem you have any problem with the iron levels.

Take care,

Q. I would like to compare old cholesterol and today´s cholesterol level. what is the difference? I would greatly appreciate your help in this. A normal value used to be 200 and now it is 4 or 5. Can anybody help.

A. Is it possible that the earlier reference range you have is in mg per deciliter (mg/dL) and the new one is in milimoll per liter (mmol/L)?

200 mg/dL worth roughly 5 mmol/L
