Math in Medical Science: Understanding Medical Applications of Math

You will be surprised to know that Math is very important in the field of Medicinal Science. You may think applications of Math in medical science are limited, as the field is all about biological and chemical processes in the body. However, Math is important in maintaining health.

Math has its applications everywhere in every field. Since it is associated with numbers and algorithms, it forms the backbone for things. In other words, knowledge of Math may be the difference between saving a patient’s life.

Medicine frequently talks about incidence and prevalence, in terms of birth rate and death rate. Math helps in calculating drug doses, doses of radiation to be given, schedule, and course of treatment. Therefore, Math is very important in the field of Medicinal Science. 

Bio-Technology is the field of biology in which Math is used to calculate the quantitý, proportion, graphs, error, and many more. In medicine, the major thing to calculate is the maximum and minimum output, so Math is used here. Biology needs Math in these cases.

Let’s discuss the importance of math in medical science with its applications:

1. Algebra

Algebra is useful to calculate dosages, create drug prescriptions, and decide the appropriate amount. The majority of doctors prescribe pharmaceutical dosage based on the patient’s weight.

2. Conversion

Most doctors recommend doses of medicine based on the patient’s body weight. Sometimes, doctors convert weight from pounds into kilograms and convert medicine into milligrams per kilogram.

Doctors then determine how long patients must continue taking medicines.

3. Statistics

Statistics certainly plays a huge role in the everyday functioning of a medical laboratory. We use quality control to ensure analyses are correct and exact.

We use normal distribution data to determine if a test is in control or out of control. Statistics is also a good player in determining the reference ranges for tests. The data first includes all healthy patients and then sorted by age and gender after that.

4. Geometry

When reading results from CAT scans and X-rays, doctors use Math. For instance, they use it to convert the two-dimensional images on the screens into three-dimensional body parts. In addition, they determine abnormalities by looking at body parts from many different angles.

5. Rate and Ratio

Rates and Ratios play an important role in understanding the health, and above all, the mortality of the population. In the areas of research, medical professionals draw charts, analyze graphs, and study statistical trends. They understand societal ailments, such as the prevalence of chronic illnesses and diseases with maths.  

6. Probability

Probability is a repeating theme in medical practice. Doctors after some experience in their profession understand that diagnosis and prognosis have varying degrees of uncertainty. They can at best be probable in a particular case.

An important challenge in biology, today, is to link knowledge about the structure of biomolecules to their function.

Genomic sequencing and advances in structural biology are starting to give a detailed view of what biomolecules look like. However, it is still challenging to infer functional characteristics from structural data.


It may seem like Maths is all about numbers and ratios. However, its applications are vast. The role and importance of Maths in medical science is no smaller than the role of biology. On the contrary, Maths is and has been leading the medical field into growth.
