Preparing a red cell suspension involves washing the red cells to remove unwanted substances like plasma proteins and antibodies that could interfere with serologic tests. This ensures a clean sample for accurate and reliable testing. Additionally, red cell suspension helps to standardize the concentration and quality of red cells used in the test, improving the consistency of results.
A red-top tube is typically used for crossmatching blood. This tube contains no anticoagulant and is used for collecting blood samples for serology testing, including crossmatching.
Red top tubes are typically used for blood collection to obtain serum samples. The red top indicates the absence of anticoagulants or clot activators in the tube, making it suitable for tests that require serum, such as blood chemistry tests or serology.
Lavender top test tubes are typically used for collecting whole blood for hematology tests, such as complete blood count (CBC) which includes white blood cell count, red blood cell count, platelet count, and hemoglobin levels. These tubes may also be used for blood bank testing, immunology, and serology tests.

The SST tube is typically gold or red-gray in color. It contains a gel separator and clot activator, making it suitable for chemistry and serology testing.
The red top tube is typically used for serology testing such as blood grouping, antibody screening, and crossmatching. It can also be used for some chemistry tests like drug levels and therapeutic drug monitoring.
Red blood cells (erythrocytes) cannot be used for karyotyping as they do not contain a nucleus. Karyotyping involves examining the number and structure of chromosomes within the nucleus of a cell, which red blood cells lack.
Chemistry, serology, immunology, toxicology and blood bank testing.
The red card suspension starts from the very next game and is usually 3 match ban . Although if the reason for the red card is severe , the suspension might be for more than 3 matches . The player can also appeal against the red card .
A hypotonic suspension would cause red blood cells to swell and potentially burst when viewed under a microscope. In a hypotonic environment, the concentration of solutes outside the cell is lower than inside, leading to water influx into the cells. This osmotic pressure can cause the cells to swell and eventually lyse (burst), resulting in the release of hemoglobin and cellular contents.
a red blood cell is red when it reaches oxegen.
