Controversial. That’s the word that comes to mind when I think about my job as a Clinical Lab Technician. Controversial because while some people might think what I do is all about test tubes and microscopes, it’s so much more than that. Being a lab tech means being a part of something bigger, something that has a direct impact on people’s lives.
So, let’s dive into it. Today, I want to talk about a hot topic in healthcare: blockchain. You might have heard about it in the context of cryptocurrencies like Bitcoin, but its potential in healthcare is immense. Blockchain is essentially a decentralized, secure, and transparent digital ledger that can store and share data across multiple parties. In the context of healthcare, it has the potential to revolutionize how we share and access patient records, improve data security, and even enable personalized medicine.
But let me shift gears for a moment and share a personal story. A few weeks ago, I had a patient who needed multiple blood tests done. As I was collecting the samples, I noticed a slight discoloration in the blood. That raised a red flag for me because I know that even the slightest hemolysis, the rupture of red blood cells, can have a significant impact on test results. So, I took extra care in ensuring a smooth and gentle draw, using the right-sized needle and choosing the appropriate site to minimize any potential damage to the blood cells.
Now, let’s talk about how to prevent hemolysis during blood collection and the impact it can have on test results. Firstly, it’s essential to choose the right size and gauge of the needle. Using a needle that is too small can cause hemolysis due to high shearing forces, while one that is too large can cause damage to the cells. Secondly, the technique used during blood collection plays a crucial role. Pulling too hard on the plunger or using a needle with a beveled edge can cause hemolysis. It’s crucial to be gentle and avoid any unnecessary trauma to the cells.
But why does hemolysis matter? Well, when red blood cells rupture, they release their internal contents, including potassium, lactate dehydrogenase, and various enzymes. These released substances can alter the results of potassium, lactate dehydrogenase, and enzyme assays, leading to incorrect diagnoses or treatment plans.
To prevent hemolysis, it’s also important to choose the correct collection tube. Some anticoagulants can cause hemolysis, so it’s necessary to use the appropriate type for the intended tests. It’s also crucial to avoid excessive agitation of the collected blood and ensure proper transportation and storage conditions. Temperature fluctuations and prolonged storage can cause hemolysis as well.
In conclusion, preventing hemolysis during blood collection is crucial to ensure accurate test results. Choosing the right needle, using proper collection techniques, and selecting the appropriate collection tube are essential steps. As a Clinical Lab Technician, it’s my responsibility to pay attention to even the smallest details and provide the best quality care to patients. Because at the end of the day, it’s about making a difference and contributing to the well-being of those we serve.
