The document discusses different types of volumetric and non-volumetric glassware used in laboratories, as well as various blood collection tubes and their purposes. Volumetric glasswares like pipettes and burettes are used to precisely measure small volumes, while non-volumetric items like beakers and flasks handle larger volumes. Blood collection tubes contain additives like EDTA, sodium citrate, or sodium fluoride that act as anticoagulants so blood can be tested for various analyses like complete blood counts, coagulation studies, or glucose levels. The document provides details on the components and common uses of tubes like SST tubes, fluoride oxalate tubes, and heparin tubes.
8. Instrument is used to measure specific
gravity.
It is calibrated for 20 ̊C temperature.
For every 3 ̊C rise in temperature,
0.001 is added to reading.
For every 3 ̊C fall in temperature,
0.001 is substracted to reading.
11. EDTA (Ethylene Diamine Tetra-Acetate) liquid:
EDTA acts as an anticoagulant, binding
the calcium ions.
These tubes are used primarily in
haematology procedures, assessing
complete blood count, bone marrow
Specimens, HbA1C ..
12. SST (Serum Separator Tube)
Contains a gel at the bottom to separate blood
cells from serum on centrifugation.
Uses: LFT, CRP, Urea, Electrolyte,
Immunology, and Serology.
13. Contains two main agents, Sodium fluoride
acts as an antiglycolytic agent to ensure that
no further glucose breakdown occurs within
the sample after it is taken. Potassium
oxalate acts an anticoagulant.
Common Tests—
Glucose—this can be fasting or non fasting,
or part of glucose tolerance test (GTT)
Lactate
15. Sodium Heparin or Lithium Heparin
anticoagulant or ammonium heparin . Acts as
an Anticoagulant by inhibiting thrombin
formation.
Uses: for collection of heparinized
plasma or whole blood for special
tests.
