What is a Hemoglobin Level Chart?

A hemoglobin level chart is a valuable medical resource that helps patients delineate the typical, elevated, and diminished hemoglobin concentration within a patient’s bloodstream, as seen in their test results. A resource such as this exists because of the importance of having the right quantity of hemoglobin, a protein found in the red blood cells that brings oxygen from the lungs to different tissues and takes carbon dioxide from those tissues back to the lungs in the body. 

On a hemoglobin level chart, you can expect to see established normal levels of hemoglobin depending on the patient’s age and gender. If you want an idea of the chart you’ll see on the template, you may refer to the hemoglobin levels below:


  • Birth: 13.5 to 24.0 g/dl
  • Less than one month: 10.0 to 20.0 g/dl
  • 1-2 months: 10.0 to 18.0 g/dl
  • 2-6 months: 9.5 to 14.0 g/dl
  • Six months to 2 years: 10.5 to 13.5 g/dl
  • 2 to 6 years: 11.5 to 13.5 g/dl
  • 6 to 12 years: 11.5 to 15.5 g/dl


  • 12-18 years old: 12.0 to 16.0 g/dl
  • Over 18 years old: 12.1 to 15.1 g/dl
  • After Middle Age: 11.7 to 13.8 g/dL


  • 12-18 years old: 13.0 to 16.0 g/dl
  • Over 18 years old: 13.6 to 17.7 g/dl
  • After Middle Age: 2.4 to 14.9 g/dL

Do remember that these values may exhibit slight discrepancies between various clinical laboratories. Furthermore, if the patient has a mildly reduced hemoglobin count, it may not indicate illness and instead present a normal range for certain individuals. 

Aside from an individual hemoglobin test, you may also use the hemoglobin chart when you’re analyzing a complete blood count test (CBC), a diagnostic tool used by healthcare practitioners to identify and evaluate any blood-related medical conditions, since the hemoglobin test is an integral part of the aforementioned test.

Hemoglobin level charts are a valuable resource that’s best to keep handy. So, make sure that you have one when the need arises by doing either of the steps below:

  • Clicking the “Download Template” or “Use Template” button
  • Searching “Hemoblogin Levels Chart” on Carepatron’s template librarys search bar on the website or app

Step Two. Input Essential Information

If you plan on using it as more than a visual aid when educating patients on normal hemoglobin levels, it’s best if you fill out essential patient details, including the test results of their hemoglobin test. 

Step Three. Compare and Contrast

Afterward, use the chart provided to compare and contrast normal levels with those found on your patient’s test results document. Don’t forget to consider their age and gender when analyzing. 

Step Four. Write Down Interpretation

On our template, you may write your observations and/or findings in the space we dedicated to interpreting results. Aside from that, if you wish, you may also utilize the space for additional notes or information to write down medical interventions you need to perform or further examinations you must conduct. 

Step Five. Securely Store the Template

Once your consultation is finished, you must securely store the template to limit access to information to relevant parties only. For digital copies, we recommend storing your document on Carepatron, a HIPAA-compliant, free patient records software that can safeguard all of the medical records, including a filled-out hemoglobin levels chart relevant to your patient.

When would you use this Chart?

A hemoglobin level chart has been a valuable tool used in several medical contexts to ascertain if an individual’s hemoglobin levels are within the established normal range corresponding to their gender and age. This resource proves extremely useful in the following scenarios:


Healthcare practitioners can use the hemoglobin levels chart to diagnose anemia and sickle cell disease. Anemia is when a patient has a red blood cell count deficiency or low hemoglobin concentration in the blood that’s usually triggered by factors like vitamin/iron insufficiency, chronic illnesses, and blood loss. Meanwhile, sickle cell disease is a hereditary disorder that affects the shape of a patient’s red blood cells and causes abnormal hemoglobin levels. 


Aside from diagnosing, the hemoglobin levels chart can also assist patients in monitoring and treating patients with anemia and sickle cell disease. With regard to anemia, the chart can be used as a monitoring instrument to evaluate the effectiveness of the prescribed therapy. 


Hemoglobin level charts also play an essential role in screening potential blood donors to ensure adequate hemoglobin levels before donating. The chart may aid healthcare practitioners in safeguarding the donor’s health and assessing if they are at risk of having post-donation anemia.

What do the results mean?

Our hemoglobin levels chart has a space wherein you can write the hemoglobin results of your patient. That way, you won’t have to jump from one document to another when you compare, contrast, analyze, and interpret. 

Although we’re well aware that you know how to utilize the hemoglobin levels chart, in case you need assistance with what your patient’s results mean in relation to the levels on the chart, here are some general interpretations:

Within the Levels

If your patient’s hemoglobin levels are within the range on the chart, after considering their age and gender, it means that the person’s red blood cells are healthy and functioning properly. 

Lower than the Normal Range

If the patient’s hemoglobin levels are less than the lower limit of the accepted normal range for their age and gender, it may indicate the potential presence of anemia or other blood-related conditions. 

You may want to check if your patient has severe blood loss, a chronic illness they haven’t told you about, or a vitamin or iron deficiency so that you may formulate an immediate and appropriate course of action for management or treatment. 

Higher than the Normal Range

If the patient’s hemoglobin levels exceed the established and accepted normal range of their age and gender, it signifies a condition that affects the blood, such as chronic obstructive pulmonary disease or polycythemia vera. It’s best to assess your patient and have them undergo further examination to identify the specific condition responsible for the deviation from normal levels. 

When using the hemoglobin levels chart, note that normal ranges may vary from one laboratory to another, and for an accurate diagnosis or treatment, you may want to consider requesting additional tests.

Research and Evidence

Hemoglobin results may seem like a much more valuable tool than hemoglobin level charts regarding patient care. The former can provide more information on the condition of your patient, while the latter can only provide you with the expected or accepted normal range of hemoglobin levels in an individual depending on their age and gender.

However, you must consider that without the latter, you won’t have a basis for what is considered deficient or elevated hemoglobin level. Hence, a need for both the results and the hemoglobin level chart for better and more accurate analysis and interpretation. 

And even though studies that support the use of a hemoglobin levels chart have been sparse, if it exists at all, one can see the value of having hemoglobin levels charts or a variation of it in articles from reputable medical websites that provide its readers with information on hemoglobin and hemoglobin levels to reports exploring conditions like anemia. In fact, identifying and establishing realistic, acceptable values for hemoglobin levels for charts for more accurate diagnosis has also been a subject for discussion. 

These, among many others, are just a glimpse of the utility of hemoglobin level charts, thus serving as enough evidence to prove its value in the medical field.
