What is the fluid for analysis (LDH + albumin) lab test?
A fluid for analysis (LDH + Albumin) lab test is a laboratory examination that measures the level of albumin and lactate dehydrogenase (LDH) in ascitic fluid.
Why is the fluid for analysis (LDH + albumin) lab test done?
A fluid for analysis (LDH + albumin) lab test is done in order to:
- Differentiate ascitic fluid into exudate or transudate.
- Find out the exact cause of accumulation of fluid in the peritoneal cavity.
What does a fluid for analysis (LDH + Albumin) lab test measure?
A fluid for analysis (LDH + Albumin) lab test measures the level of albumin and lactate dehydrogenase (LDH) in the ascitic fluid. Albumin is a protein that helps in retaining fluid in the bloodstream. Lactate dehydrogenase (LDH) is an enzyme that helps in converting sugar into energy for the cells.
Are there any risks associated with this test?
There is a risk of excessive bleeding, infection, low blood pressure, and shock.
How should I prepare for this test?
This test does not require any special preparation.
How ascitic fluid is collected?
A health care practitioner will clean and numb a small area of your belly area (abdomen). A needle is inserted through the skin of your abdomen and a fluid sample is pulled out. The fluid is collected into a tube (syringe) attached to the end of the needle.
Can I eat and drink before this test?
You can eat and drink normally before the test unless your doctor asks you to fast.
Is it normal to have peritoneal fluid?
The peritoneal space is typically empty or contains a small amount of fluid. But a build-up of fluid can occur if you have a disease or infection.
Serum ascites albumin gradient greater than 1.1 g/dL means that the ascitic fluid is a transudate.
Serum ascites albumin gradient less than 1.1 g/dL means that the ascitic fluid is an exudate.
Lactate dehydrogenase serum to fluid ratio less than 0.6 means the fluid is a transudate.
Lactate dehydrogenase serum to fluid ratio greater than 0.6 means the fluid is an exudate.
A fluid for analysis (LDH + albumin) lab test is done in order to:
