How to graph blood test results

Blood test results are usually graphed, using a graphical representation of the data to help you see how your results compare to a normal test. You can also use the chart to predict future trends in your test levels. Line charts compare two variables (pieces of data) and can be used to perform a variety of blood tests, including complete blood counts, vitamin levels, and glucose tolerance tests, graphically to represent.

Draw a 10 inch horizontal line with your ruler. Make tick marks every inch. Label this line "Time". Blood tests are sometimes done every 30 minutes or an hour. Sometimes they can be used to track trends over weeks or months. Choose a label that best fits your test. For example, if you are graphing a 5-hour glucose tolerance test, label the graph "Time (Minutes)" or "Time (Hours)".

Label the tick marks on the horizontal axis (the line you just drew). For example, if you wrote "Time (Hours)", you would mark the tick marks in an hour (1, 2, 3, 4, 5) or 30 minutes (0.5, 1, 1.5, 2, 2, 5, 3, 3.5, 4, 4.5, 5) intervals.

Draw a vertical axis. In the far left corner, draw a straight line an inch from the top of the page. Label this line with your measured variable. For example, if a glucose tolerance test measures blood sugar (mM), that line would label "Blood Glucose (mM)".

Place marks every inch on the vertical line. Label with the appropriate measurement. For example, glucose levels can be measured in 4mM increments, so label the tick marks 4, 8, 12, 16, 20. The values ​​should start at the bottom and increase as they go up.

Plot your data. Take the first data set and make a point on your graph where the two lines intersect. For example, if the first reading is 5 mM at 0 minutes, draw a line from 0 up and a 5mM line straight up. Make a point on the diagram where the two lines intersect. Drawing actual lines is optional: your diagram will look better if you draw imaginary lines with your finger.

Repeat step five for all data points.

Connect all data points with a single line from the left (on the vertical axis) to the last data point on the right.
