Biomedical science postgraduate personal statement example

Personal statement example

Every afternoon at about half past three, a courier arrives at the GP surgery where I work to collect the day's blood samples. Before then I check each tube against its request form: name, date of birth, the right coloured cap for the test requested, the time the sample was taken. It is a small job, but I have come to understand why it matters. A full blood count in the wrong tube, or a potassium sample left too long before processing, can give a result that looks meaningful and is not. That gap between the patient in the chair and the number that eventually appears on the GP's screen is what I want to study at postgraduate level.

My BSc in Biology, where I achieved a 2:1, gave me a broad grounding in cell biology, genetics and microbiology, and I chose options in immunology and human physiology because they connected most directly to disease. My final-year project screened bacteria isolated from soil samples for antimicrobial activity. I cultured isolates, tested them against non-pathogenic strains of Escherichia coli and Staphylococcus epidermidis using agar overlay and disc diffusion, and measured zones of inhibition. Two isolates produced consistent zones, though I lacked the time to characterise what they were secreting. The most useful skill I gained was not a technique but a habit: recording conditions precisely enough that a repeat would mean something. When one plate gave a much larger zone than its replicates, my notes showed it had been poured thinner, which explained the difference.

I took my current job, as a receptionist who also supports the practice nurses with clinic preparation and sample handling, intending it as a year to save money. It has turned into the reason I am applying. I have no clinical responsibility, but I see the routine side of diagnostics constantly: repeat HbA1c checks for patients with diabetes, INR monitoring for those on warfarin, thyroid function tests. Seeing how often treatment decisions depend on these results made me read more about how they are produced. I worked through sections of a clinical biochemistry textbook on electrolytes and renal function, and I now understand why haemolysis falsely raises potassium, something I had only been told to avoid before.

I am particularly interested in haematology and clinical biochemistry, and in how laboratories maintain reliable results through quality control and calibration. My undergraduate course touched on these only briefly, and I want the deeper theoretical knowledge and hands-on laboratory experience that a master's degree in biomedical science would provide. In the longer term I would like to work in an NHS pathology laboratory, and I understand that this path involves further training and professional registration beyond a degree.

Outside work, I help on Saturday mornings at a food bank run from a church hall near where I live. I started by packing parcels and now help coordinate the volunteer rota and the stock log, which has made me more organised and comfortable dealing with people who are often having a hard week. I also play in a five-a-side league on Tuesday evenings, mostly as a defender, which keeps me sane in a week of early starts.

I am conscientious, accurate and used to balancing study-level reading with full-time work. My project taught me to be patient with results that do not immediately make sense, and my job has shown me that laboratory science has real consequences for ordinary people. I would bring both to postgraduate study, along with a genuine curiosity about what happens to those tubes after the courier drives away.
