What is the use of Microcapillary tube?
Micro-capillary tubes, ideal for spotting TLC plates or chromatography paper, thanks to the small volume of liquid contained within each narrow bore tube. The liquid to be spotted is drawn up into the glass tube by capillary action and will be drawn back out by touching the end onto a TLC plate or chromatography paper.
What are the three types of capillary tubes?
There are 3 types of capillary in the body; continuous, fenestrated, and sinusoidal.
Should I use EDTA or heparin tube?
EDTA is most often used when you want to do hematological tests (red and white blood cell count, Hb, blood group), citrate for example damages cells so won’t we useful. Heparin is used for clinical chemistry tests such as cholesterol, CRP, hormones etc. It interferes with PCR, so if you want to do that use EDTA.
What are the different types of heparin tubes?
The green tubes contain heparin (can either be in the form of sodium heparin, lithium heparin, or ammonium heparin), which acts as an anticoagulant by inhibiting thrombin formation. Unlike red tubes, the type of blood produced in a green tube needed for testing is not serum but plasma.
What makes capillaries different from other blood tubes?
Veins have thicker walls than capillaries. Veins use valves to transport blood towards the heart, but capillaries don’t have valves. Capillaries diffuse blood and nutrients between veins and arteries through their thin walls.
Which is the most common type of capillary?
Continuous Capillaries The most common type of capillary, the continuous capillary, is found in almost all vascularized tissues. Continuous capillaries are characterized by a complete endothelial lining with tight junctions between endothelial cells.
Are all capillaries the same?
There are two types of capillaries: true capillaries, which branch from arterioles and provide exchange between tissue and the capillary blood, and sinusoids, a type of open-pore capillary found in the liver, bone marrow, anterior pituitary gland, and brain circumventricular organs.
What is a plain capillary tube used for?
If collecting anti-coagulated blood from a blood collection tube, use a plain capillary tube. If collecting by finger stick from a patient or when using untreated blood, use capillary tubes that are treated with an anticoagulant (heparin).
What is the difference between a capillary tube and micro collection tube?
Microcollection tube: [aka bullets], small tube used to collect dermal puncture samples. Capillary tube: [aka microhematocrit tube], small plastic tubes used primailry for hematocrit tests.
What type of tube is used for capillary puncture?
Microcontainer tubes are specially designed small plastic tubes used to collect minute volumes of blood via capillary puncture.
Which tube is not centrifuged?
EDTA tubes for hematology testing should not be centrifuged at all and should be maintained as whole blood.
Do EDTA tubes get centrifuged?
EDTA plasma This is the supernatant that is removed after centrifugation of blood collected in a lavender (purple) top tube. This sample should be labeled with the owner name, animal ID, and the words “EDTA plasma”. This is the sample needed for ACTH endogenous and ACTH & insulin.
What are 2 uses of capillary tube?
The main aim of the capillary tube is to reduce pressure. It is used in laboratories for collecting the different samples of liquid. It is used for checking concentrations, molarity, molality, etc. Capillary tubes can be used in refrigeration to control the flow of refrigerants.
What are the two capillary systems?
The other two capillary networks are the glomerular capillaries and vasa recta. The peritubular capillary beds maintain low blood pressure that allows them to easily absorb fluids and nutrients. Peritubular capillaries reclaim molecules that help your body function, like amino acids, glucose, and minerals.

How do you fill a heparinized capillary tube with blood?
Alright, so you’re probably here because you’re curious about the difference between heparinized and non-heparinized capillary tubes. These little tubes might seem simple, but they play a crucial role in blood collection. Let’s dive in and break down the differences so you can understand which one is right for your needs.
Heparinized Capillary Tubes: A Quick Overview
Heparinized capillary tubes are coated with heparin, a natural anticoagulant. This means they prevent the blood from clotting inside the tube. Think of heparin as a tiny bodyguard for your blood sample, ensuring it stays liquid and ready for testing.
Non-Heparinized Capillary Tubes: The Plain Vanilla Option
Now, non-heparinized capillary tubes are just that: plain and simple. They don’t contain any anticoagulants. So, what does that mean for your blood sample? Well, the blood will start to clot inside the tube.
Why the Difference Matters
The choice between heparinized and non-heparinized capillary tubes depends entirely on the type of blood test you’re doing. Let’s break it down:
Heparinized Capillary Tubes: When They’re the Perfect Match
Hematology Tests: If you need to analyze the blood cells, like for a complete blood count (CBC) or differential, heparinized tubes are your go-to. They’ll preserve those precious blood cells, keeping them from clumping together.
Chemistry Tests: Many chemistry tests also call for heparinized tubes. They ensure your blood sample remains stable and accurate for testing.
Non-Heparinized Capillary Tubes: The Best Choice for Some Tests
Blood Glucose Monitoring: Here’s where non-heparinized capillary tubes shine. They’re perfect for measuring blood sugar levels because the clotting process doesn’t interfere with the testing method.
Blood Smears: When making blood smears for microscopic analysis, non-heparinized tubes are the way to go. The clotting process helps to spread the blood cells out, making them easier to examine.
How to Use Each Type: A Quick Guide
Heparinized Capillary Tubes: To use them, you’ll usually need to pierce your finger with a lancet, then gently squeeze the tube to collect blood.
Non-Heparinized Capillary Tubes: These are typically used in combination with a lancet. You’ll collect blood by touch, allowing it to fill the tube by capillary action.
Storing Your Capillary Tubes: Keeping Things Safe
No matter which type of tube you’re using, it’s important to store them properly. Here are some quick tips:
Cleanliness: Always work with clean hands and surfaces.
Proper Labeling: Label each tube with the patient’s name and any other relevant information.
Safe Storage: Store capillary tubes in a cool, dry place, away from direct sunlight.
The Lowdown: Making the Right Choice
Remember, selecting the right type of capillary tube depends on the specific test you’re performing. Always check the instructions provided with your test kit or consult with a healthcare professional if you’re unsure.
