Depends on the test.
Only a tiny drop from the tip of your finger. no pain at all. ( When this type test is made using a blood test device in drugstores (if they are allowed to perform it). I my country it is an usual practice. When you make this test through a laboratory office, the amount of blood is about 3 ml.
Tumor marker tests usually require 5-10 mL of blood.
Most DNA tests are done using mucosal cells or hair follicles. Simpler, cleaner and less of a biohazard. Blood tests are much less accurate. The methods used for the original blood tests in TB horses used 6 mls of blood. Actual amount needed would depend on how fresh the blood sample is.
The volume of blood needed for laboratory analysis varies widely with the type of test being conducted. Typically one or several small (5-10 mL) tubes are drawn.
The cost of a blood test for a cat with liver failure can vary depending on the veterinary clinic, location, and specific tests needed. In general, blood tests for liver function typically range from $50 to $200. Additional tests or consultations may be necessary, increasing the overall cost.

There are multiple types of blood tests ranging from a complete blood count to testing very specific blood properties such as iron levels. Typically, blood is removed with a needle from a vein or artery in the arm. The amount of which is determined by the number of tests that will be run on the blood. If only a small amount of blood is needed. like that of an iron test, blood will be obtained from a finger prick.
Blood sugar tests include several different tests that measure the amount of sugar (glucose) in a person's blood.
Hematological tests that require venipuncture include complete blood count (CBC), blood typing and crossmatching, and coagulation studies such as prothrombin time (PT) and activated partial thromboplastin time (aPTT). These tests assess various components of blood, including red and white blood cells, platelets, and clotting factors. Venipuncture is preferred over capillary sampling for these tests due to the larger volume of blood needed and the need for accurate results.
There is no fasting needed for a CBC. If other blood tests are needed, you might need to fast for twelve hours before the test.
alot.
1 ml blood is ok for blood culture
No because the "patients" you will find at a funeral home no longer have a working blood flow. A coroner will handle all tests needed to be preformed.
