Medical test Reference Ranges for Adults in good physical condition test
Published: 14 Jan 2024
Taking blood samples from patients is typically used in order to analyze aspects of the individual's health.
It can allow doctors to diagnose any potential blood-related and non-blood related disorders, as well as monitoring the progress of conditions and effectiveness of treatments.
Several factors can be measured during laboratory analysis of the samples, including complete blood count, hormone and electrolyte levels, types of leukocytes, and levels of blood plasma protein.
To establish the presence or absence of a range of medical conditions, the patient's blood properties can be analyzed, and comparisons made to a set of healthy or normal values known as 'reference ranges'.
A reference range may also be called 'normal values.' You may see something like this on your results: 'normal: 77-99mg/dL' (milligrams per deciliter). Lab results are often shown as a set of numbers known as a reference range. If you get an inconclusive result, you will probably get more tests.
Tests that measure various organs and systems often give results as reference ranges, while tests that diagnose or rule out diseases often use the terms listed above.If your results fall outside the reference range, or if you have symptoms despite a normal result, you will likely need more testing.
Your lab results may also include one of these terms:
Negative or normal, which means the disease or substance being tested was not found
Positive or abnormal, which means the disease or substance was found
Inconclusive or uncertain, which means there wasn't enough information in the results to diagnose or rule out a disease. Reference ranges are based on the normal test results of a large group of healthy people. Sometimes, healthy people get results outside the reference range, while people with health problems can have results in the normal range. The range helps show what a typical normal result looks like.
But not everyone is typical.
