Hello, dear readers! Are you curious about in which cases are assigned and how is the blood test for chicken pox?
In this article I will describe in detail how to prepare for this procedure, how to decipher the results and why to donate blood with the pox. An enjoyable read.
Some General information
Varicella virus provokes Varicella-Zoster related to the family of herpes viruses. The disease is highly contagious and is transmitted in various ways:
- airborne (the most dangerous route of transmission of viruses);
- in contact with the contents of the rash (very rarely, but it happens).
The patient is infectious 2 days before and for 5 days after the appearance of watery pimples. Smallpox had been ill for the second time does not appear, however, the virus remains in the body in a latent state. The threat of virus activation create different types of immunodeficiencies. If it is activated, then the person develops shingles.
Chickenpox is diagnosed by clinical, based on symptoms such as watery rash on the skin and mucous membranes. But sometimes the disease is atypical. How to determine it in this case? This will help check the blood for antibodies to varicella.
How is such a study? In fact, logical and simple: «Antibodies IgM and IgG to virus of Varicella-Zoster».
If reveals IgM antibodies means viral infection has acute or recently. In some cases, IgM antibodies circulate in the blood until a year after suffering illness. If they find IgG antibodies means you have immunity to chicken pox since you had it in the past.
In some cases, is assigned to check for chicken pox?
Sometimes this disease appear uncharacteristic symptoms:
- uncharacteristic rash;
- the lack of symptoms, etc.
In such cases, the diagnosis solely on clinical presentation is difficult. In children, smallpox is nearly always standard. But adults sometimes suffer a similar deviation.

For example, you have a sick child, and you are pregnant with a second. In order not to jeopardize the health of future child, you need to check whether you have specific antibodies IgM.
If they are, then it is necessary to carry out the prevention of viral disease. But if you show up IgG, we can not worry about their health as well as immunity to the virus is already there.
Price and features of the procedure
Blood is taken in a standard way and checked for the presence of antibodies to the virus. The study is carried out very reliably and very specific. Probably, such procedure is very expensive, you ask. The price is not so high:

These studies can tell a lot about the state of the body of the sick viral disease. The result was probably accurate, you need to prepare for blood donation. Therefore, I suggest to read the rules that must be followed before donating blood on a windmill.
